Dreamy Hawaii

I really enjoyed this visual story by ProPublica and Honolulu Star-Advertiser about the plight of beaches in Hawaii (link). The story begins with a beautiful invitation: This design reminds me of Vimeo's old home page. (It no longer looks like this today but this screenshot came from when I was the data guy there.) In both cases, the images are not static but moving. The tour de force of this...

I made a streamgraph

The folks at FiveThirtyEight were excited about the following dataviz they published last week two weeks ago, illustrating the progression of vote-counting by state. (link) That was indeed the unique and confusing feature of the 2020 Presidential election in the States. For those outside the U.S., what happened (by and large) was that many Americans, skewing Biden supporters, voted by mail before Election Day but their votes were sometimes counted...

Election visuals 4: the snake pit is the best election graphic ever

This is the final post on the series of data visualization deployed by FiveThirtyEight to explain their election forecasting model. The previous posts are here, here and here. I'm saving the best for last. This snake-pit chart brings me great joy - I wish I came up with it! This chart wins by focusing on a limited set of questions, and doing so excellently. As with many election observers, we...

Ask how you can give

A reader and colleague was frustrated with the following graphic that appeared in the otherwise commendable article in National Geographic (link). The NatGeo article provides a history lesson on past pandemics that killed millions. What does the design want to convey to readers? Our attention is drawn to the larger objects, the red triangle on the left or the green triangle on the right. Regarding the red triangle, we learn...

Twitter people UpSet with that Covid symptoms diagram

Been busy with an exciting project, which I might talk about one day. But I promised some people I'll follow up on Covid symptoms data visualization, so here it is. After I posted about the Venn diagram used to depict self-reported Covid-19 symptoms by users of the Covid Symptom Tracker app (reported by Nature), Xan and a few others alerted me to Twitter discussion about alternative visualizations that people have...

This exercise plan for your lock-down work-out is inspired by Venn

A twitter follower did not appeciate this chart from Nature showing the collection of flu-like symptoms that people reported they have to an UK tracking app.  It's a super-complicated Venn diagram. I have written about this type of chart before (see here); it appears to be somewhat popular in the medicine/biology field. A Venn diagram is not a data visualization because it doesn't plot the data. Notice that the different...

Graphing the extreme

The Covid-19 pandemic has brought about extremes. So many events have never happened before. I doubt The Conference Board has previously seen the collapse of confidence in the economy by CEOs. Here is their graphic showing this extreme event: To appreciate this effort, you have to see the complexity of the underlying data. There is a CEO Confidence Measure. The measure has three components. Each component is scored on a...

Gazing at petals

Reader Murphy pointed me to the following infographic developed by Altmetric to explain their analytics of citations of journal papers. These metrics are alternative in that they arise from non-academic media sources, such as news outlets, blogs, twitter, and reddit. The key graphic is the petal diagram with a number in the middle. I have a hard time thinking of this object as “data visualization”. Data visualization should visualize the...

Bubble charts, ratios and proportionality

A recent article in the Wall Street Journal about a challenger to the dominant weedkiller, Roundup, contains a nice selection of graphics. (Dicamba is the up-and-comer.) The change in usage of three brands of weedkillers is rendered as a small-multiples of choropleth maps. This graphic displays geographical and time changes simultaneously. The staircase chart shows weeds have become resistant to Roundup over time. This is considered a weakness in the...

Tennis greats at the top of their game

The following chart of world No. 1 tennis players looks pretty but the payoff of spending time to understand it isn't high enough. The light colors against the tennis net backdrop don't work as intended. The annotation is well done, and it's always neat to tug a legend inside the text. The original is found at Tableau Public (link). The topic of the analysis appears to be the ages at...
