Hey folks, Are you interested in uping your data visualisation skills? I’m rolling out a new program to help you improve the design of your data visualizations. This program will last 5 weeks starting at the beginning of September. Each session will be two hours long and include a discussion of data visualization principles followed by an opportunity to apply these ideas to your own visualizations. There will be no coding in this program so you can focus more on concepts than implementation. I believe that once you understand the concepts, you can use any tool - even a pencil and piece of paper - to implement your design. Click this button to learn more.
In recent weeks there’s been a kerfuffle about data coming out of the government. Specifically the US Bureau of Labor Statistics (BLS) revised its forecast of the number of jobs created in May and June 2025 by about 125,000 jobs per month. This led President Trump to fire the Chief of the BLS. Obviously, it’s critical to have trustworthy data from the government to understand the state of the economy, assess effectiveness of programs, and track the overall health of society. Political firings of people implementing SOPs is jarring. Beyond the politics, the NY Times again had a visualization that I found interesting. There are a few things in this figure that I found interesting and that I am curious to try out in R with First, this plot is a stacked bar chart. I really like the use of negative space for the number of jobs that were over projected in May and June. I’d start by making sure the data are in a tidy format with a column for the date (first of each month month and year between July 2024 and July 2025), a column for the number of jobs, and a column to indicate whether the number of jobs is from firm estimate or over projection. With this structure, we could use Second, I really liked the use of color. For the preceding months and years the firm numbers are in gray while the projected extra numbers are white. But for July 2025 the number is in orange. This would mean that we need three values in the indicator column. We could use Third, there’s a couple of instances of annotation in the plot. The first that catches my eyes is the italicized “REVISED DOWN” over the bars for May and June 2024. I’d likely do this with Finally, in classic New York Times fashion the y-axis labels are on top of the horizontal grid lines. It feels like it’s been a while since I’ve done one of these. I suspect I’d again use What do you think of this visualization? Did you notice anything that I’ve glossed over? How would you go about implementing that flourish?

Hey folks! I’m appreciating the positive feedback on Monday critique videos. They’re a lot of fun to think through and make. I think I might start looking at figures that are drawn from the scientific literature since many of you found out about me from my science work. Let me know if there are plots or practices that you’d like to see me talk about. I’ll see if I can work them into the queue. Also, if you’re working on developing figures for a presentation, poster, or paper and would like to...
Hey folks! I continue to get positive feedback about my critique videos. This has me quite excited that I’ve perhaps scratched an itch that people have been struggling with. Would you like to meet with a group of other people who are committed to making their data visualizations better? I’m forming groups now that would meet once a week or every other week to give each other constructive feedback on the visualizations they are making for their work. Alternatively, if you have ever thought, “I...
Hey folks! I posted two videos last week! On Monday I posted a video critiquing the diverging bar plot that I described in this newsletter last Friday. My goal in this video was to think through a “constructive” approach to interpreting and critiquing data visualizations. As scientists, I think we are too worried about hurting each other’s feelings. So we don’t critique each other. At the same time, many of us think before we speak and can come off overly harsh. My goal is to create a...
