what comes next?

"This session was amazing. How can I continue to develop my storytelling and presenting skills?" Participants frequently ask this question at the end of our workshops.

Applying new learnings at work can be challenging because time is limited, and it's easy to fall into old routines and unhelpful habits. The best advice to develop better data storytelling skills is simply to do it. Make effective communication a goal, practice regularly, and seek feedback. 

If you're unsure how to begin, I recommend building momentum by starting small in a safe space where changes will have a positive impact and be well received. The Let's Practice! book outlines a number of exercises for practicing at work and with your team. You can also join our free online SWD community to practice on your own in a low-stakes environment, outside of your workplace.

For more hands-on, external support to hold you accountable and keep up your energy and focus on this important area, we invite you to join our 8-week online course—we have cohorts starting in June and September. This unique and immersive program allows participants to explore topics in depth during weekly lectures and through various resources (the books, blog, podcast, videos, and exercises) for a robust learning experience. The course includes optional weekly office hours to discuss and get feedback directly from data storytellers based in the US and UK so there are options that work for everyone around the world—to chat and get questions answered. Perhaps even more exciting is meeting a diverse group of fellow data enthusiasts eager to learn and grow!

No matter what approach you take to continue your development, we highly encourage you to celebrate your progress. Share success stories to track your progress, and so others can learn and be inspired. Have you found success keeping up momentum in other ways? What do you or your team do to maintain a focus on effective communication and data storytelling? Leave us a comment below with your thoughts and ideas!

Due to the highly immersive nature of the online course, enrollment is limited—secure your spot today! Attend our summer session, which runs from June 3, 2024 through July 28, 2024; or, join our fall cohort, starting on September 23, 2024 and ending on November 17, 2024. 

Past participants have expressed appreciation for the practical and actionable lessons—here is a sampling of praise the course has received:

  • “I cannot believe the presentation I was able to create and deliver in 2 months! The skills I learned, nicely paced out over 8 classes, were invaluable for delivering more effective presentations. I really appreciated the insightful feedback from the instructors on each assignment. I had many lightbulb moments regarding how to be more effective that I know will stick with me thanks to the combination of lectures and hands-on learning. This class was invaluable!” - Cathy T.

  • “It is the best training experience I have ever had! It offers all kinds of ways to learn and get feedback.” - Yuan G.

  • “I really enjoyed the course, which has given me so many new perspectives and ideas! The exercises, as well as the weekly learning resources on the course website, are the parts I liked the most. I appreciate that you offer resources in a variety of formats (read, listen, watch).” - Jessica B.

#SWDchallenge: when every point matters

 
 

The visualisation tools we have at our disposal do a great job of summarising our data. We can aggregate it ourselves with formulas (like averages, counts or sums) or we can let a viewer apply filters to customise the view. These techniques can make a visual more digestible for our audience.

Occasionally, we might find it tempting to share all of the data in its purest form, with no aggregation or restriction. In most cases, it doesn’t make practical sense to share all this information in one visualisation.  (A good friend once told me—when I tried to visualise every professional golfer’s tee-off shot over the course of ten years—it can resemble “a hot mess.”)

Quite some years ago now, I succumbed to the temptation of sharing everything. I built and proudly presented a scatter plot showing the performance vs the activity of 300 individual sales people. I can still picture the raised eyebrows and titling heads of my audience, as they struggled to make sense of the page in question. I can assure you, it isn’t a cherished memory. 

As I reflect, though, I don’t believe that the visual was necessarily the wrong choice. My downfall was in failing to clarify the insights I had observed when analysing the content. I could have pointed out the sales reps in a particular area who were struggling, highlighted the individuals who valued sales over activity, or drawn attention to those who spent too much time talking with clients without ever closing the deal. 

Challenge

Using a data set of your choice, create a visualisation that shares the data in its purest, unaggregated form. (For example, instead of showing a count of customers per region, each customer should be represented. Or, to provide a non-business example, rather than sharing the average number of shots per game a soccer striker has taken, plot the location of each of these shots.)

But, here comes the critical part of the challenge! Don’t fall into the trap I did by sharing this content without a clear message and risk overwhelming your audience. Ensure your design delivers a compelling message, using whatever techniques you prefer to make that insight clear. 

Share your designs in the community by May 31st at 5 PM PT. If there is any specific feedback or input that you would find helpful, include that detail in your commentary.

everything they need, nothing that they don't

I’ve always had a fascination with the discipline of “wayfinding,” which is a term describing the ways architects, city planners, designers, and artists make it as easy as possible for people to navigate unfamiliar places.

Think back to the last time you visited an amusement park, attended a sporting event or large concert, or passed through an airport or a public transportation system. These venues are visited by tens of thousands of people in a single day, many of whom have never been there before. For the enjoyment and safety of everyone, it’s critical (and, in many cases, legally required) that there be clear, visible, and authoritative signage physically present to help people get around the space and find what they’re looking for.

What’s fascinating to me is that wayfinding is so frequently context-specific. Rather than just posting maps of the whole airport, amusement park, or stadium, wayfinding is based much more around where you, the visitor, are standing at that moment. From there, the best wayfinding provides clear signage and path markings for the most likely things you might want to do, information you might need to know, or places you might want to go, based on the simple fact that you’re in that specific spot at that specific time.

It reminds me of being a kid in the pre-smartphone area, and how we used to provide one another personal wayfinding information. I grew up in the 80s, and if I were trying to tell a friend how to get from their house to my house, I couldn’t just fire up Google Maps on my phone—my phone was a landline, permanently connected to the wall of my family’s kitchen. I also wouldn’t pull out a Rand McNally road atlas, or visit my local American Automobile Association chapter to build a customized TripTik.

Instead, I would draw my friend a little map. I’d put some landmarks on there—maybe the streets they would need to go onto to get to my house, a couple of notable buildings they would pass along the way, and maybe some other context as needed. What they’d be left with is a piece of paper that contained everything they needed, and nothing that they didn’t. 

Here’s an example of a map I’d draw to tell my friend how to bike from our high school (1) to my house (6). “Turn left out of the high school parking lot and (2) go down the big hill. Be careful because of the (3) railroad tracks at the bottom. (4) Cross Main Street; St. Anthony’s will be on the left. At the split (5), if you go right you’ll end up at the Harbor, so go left instead until you see my house (6) on the left. It’s a green house with a blue door. If you get to (7) the police station you’ve gone too far.”

This is what we should aspire to include in the communications we show to our audiences. Sharing all of our data and all of our analysis in our presentation slides is like putting a giant, static satellite map at the entrance to an amusement park, and expecting that to be sufficient for visitors to find their way.

Far from being enough, that map would be overwhelming and way too detailed, and would only cause frustration and confusion. After all, when you’re in unfamiliar territory, you just want someone to point you towards what you need and where you’re supposed to go.

Keep this model in mind when you create slides or graphs for your audience:

  1. Follow the principles of wayfinding—give people only as much as they need, based on where they are. By putting yourself in the shoes of the people listening to your presentation and thinking about what they need, you’ll better position the content you deliver to meet their specific interests.

  2. Literally and figuratively, a simplified, custom map is easier to follow than a comprehensive and detailed one. A satellite map, while absorbing and visually interesting, contains so much detail that it can overwhelm and distract your audience. Start instead from a literal blank page, and think critically about what information needs to be included in the specific map you’re creating—and more importantly, what can be left out.

With this approach, much like the wayfinding systems we’ve grown to rely upon, your presentations will be even better positioned to provide the timely direction and guidance your audience needs.

it's okay to use multiple graphs

A tip I regularly share when providing data visualization feedback is to use multiple graphs instead of packing several series into a single chart. Although it is important to be concise, people are often surprised to hear that when it comes to the number of graphs we share, fewer isn't always better.

Let's consider an example.

A project manager is overseeing the final stages of an effort to implement a large number of feature requests for their software. The team aims to tackle the backlog of request tickets by the end of the year. They update their progress at a bi-monthly meeting, starting with an overview of ticket volumes. Once they've shared the big-picture figures, they update meeting attendees on the backlog workflow, which is divided into three stages: In Queue, In Progress, and Documentation. Below is the slide they updated and shared at the December 14th meeting.

I have some immediate thoughts on how to improve this data communication. For example, the graph is busy. It would benefit from removing visual clutter like the multiple colors, data labels, legends, gridlines, and lack of alignment. The text on the right could be better integrated into the communication so that it doesn’t feel like a separate entity.

While these suggestions could help improve the effectiveness of this communication, my biggest concern is that a single-line chart doesn’t support the two-part narrative shared above.

This is an instance where we’d be better served with two graphs—one for totals, and one for the backlog—instead of one that tries to cover everything all at once.

I already appreciate the benefits of having multiple charts. 

For one, it’s easier to process. Having fewer series makes each graph simpler to understand. I can also more easily see how the series relate to one another. The backlog total and closed tickets sum to the ticket total. The series in the right-hand-side graph sum to the backlog total shown on the left. While someone with the patience to do math could arrive at a similar understanding using the original view, why make them do extra work?

I’ll also point out that the project manager’s update typically starts with a big-picture discussion on how the total volume of tickets has changed, and then moves into the backlog details. Having a graph for each part of the narrative makes it easier for the audience to focus on the data being discussed. 

Second, there is more flexibility in design. Within a single graph, each line has to be formatted similarly. However, with two graphs, I have more flexibility in designing each narrative component separately.

For example, the vertical axis range of 0-600 is too broad to see the smaller volumes of the backlog trends, which range from a minimum of three to a maximum of 46. Pulling these lines into their own view allows me to adjust the range to something more appropriate, like 0 to 60. 

Also, I have the freedom to use different chart types. I might want to emphasize the underlying part-to-whole relationship between the closed and backlog series aggregating to the total. I can do that with a stacked bar chart.

Neither of these changes would have been possible when using just one graph.

An important consideration when multiple graphs are shown together is to visually connect them so the reader understands how they relate. In this case, I’ll do so by using a single color (bright blue) for all of the backlog series. I’ll also take the opportunity to reduce the visual clutter mentioned at the start of this critique and add the descriptive text from the original. 

My final redesign looks like the following.

While this redesign incorporates changes beyond using more than one graph, many of these improvements wouldn’t have been possible if I had not first decided to use multiple graphs.

The next time you visualize several series with different levels of detail or varying magnitudes, consider whether your communication would be better served by breaking it into two or more views. As fellow data storyteller, Mike, often says, pixels are free! 

No rule says we have to limit ourselves to a single visual. It might seem like a more efficient use of space and time to create less, but efficiency should not sacrifice the ability to communicate clearly.

#SWDchallenge: Napoleon's April

in

The other day I was watching the recent Apple-produced movie Napoleon, featuring Joaquin Phoenix as Napoleon Bonaparte and Vanessa Kirby as his first wife Joséphine. 

I’m not a history buff by any means, but I have a passing knowledge of the French Revolution and of Napoleon’s brief reign in the early 19th century. While I did not necessarily know the details of each step in his various conquests and power consolidations, I was aware that the decision to invade Russia would be disastrous for Bonaparte.  

How did I know this? It’s because one of the world’s most famous data visualizations is specifically about his catastrophic march to Moscow, and subsequent winter retreat, in 1812.

Charles Minard’s famous visualization of Napoleon’s march to, and retreat from, Moscow in 1812.

Charles Minard’s visualization, hailed by many (Edward Tufte, most vocally) as one of the greatest achievements in graphic representation of data, shows us in brutal detail the shrinking size of Napoleon’s army as he marches from France all the way to Moscow, and then back home again in defeat. The width of the line shows the number of French soldiers; the map shows their position as well as the date the army passed each location; other dimensions included in the visual are the temperatures during the winter portion of the army’s march, the geographic features (such as rivers) affecting travel, and the moments when the army split into multiple forces of varying sizes.

Far be it from us to say we could improve upon this highly regarded visual. But that’s not to say that there aren’t other ways to visualize some or all of this data—and some of these approaches may be better suited for particular audiences or scenarios. As a statistical data visualization, Minard’s map succeeds in showing multiple aspects of a single time series within one unified, static view. At the same time, it demands its readers spend considerable time to engage with it, to learn how to read it, and to synthesize every aspect of the visual at one time—which may be a challenge.

Speaking of a challenge…

This month’s challenge

This month, your challenge is to use the same data Minard used for his map. Create an alternative visualization for Napoleon’s ill-fated march on Moscow. You could choose to build a map, a static visual, an infographic, an interactive website, a PowerPoint presentation, a dashboard, or a video…just about anything you like. 

NOTE: While you may be tempted to simply rebuild a replica of this famous graph in your own visualization tool of choice, that is NOT what the challenge is about. We are asking you to create, not re-create.

Share your creation in the SWD community by Tuesday, April 30 at 5PM PT. Take some time to browse others’ submissions and share your input via comments and datapoints during the month. We look forward to seeing your creative approaches!
