Visualizing composite ratings

A twitter reader submitted the following chart from Autoevolution (link): This is not a successful chart for the simple reason that readers want to look away from it. It's too busy. There is so much going on that one doesn't know where to look. The underlying dataset is quite common in the marketing world. Through surveys, people are asked to rate some product along a number of dimensions (here, seven)....

Chicken egg color spectrum

Eggs aren’t always white, which is oddly calming in this photo. (I couldn’t figure out where this picture was originally from. Anyone?) Tags: color, egg, physical

Visual design is hard, brought to you by NYC subway

This poster showed up in a NY subway train recently. Visual design is hard! What is the message? The intention is, of course, to say Rootine is better than others. (That's the Q corner, if you're following the Trifecta Checkup.) What is the visual telling us (V corner)? It says Rootine is yellow while Others are purple. What do these color mean? There is no legend to help decipher it....

Getting to first before going to second

Happy holidays to all my readers! A special shutout to those who've been around for over 15 years. *** The following enhanced data table appeared in Significance magazine (August 2021) under an article titled "Winning an election, not a popularity contest" (link, paywalled) It's surprising hard to read and there are many reasons contributing to this. First is the antiquated style guide of academic journals, in which they turn legends...

Graphing highly structured data

The following sankey diagram appeared in my Linkedin feed the other day, and I agree with the poster that this is an excellent example. It's an unusual use of a flow chart to show the P&L (profit and loss) statement of a business. It makes sense since these are flows of money. The graph explains how Spotify makes money - or how little profit it claims to have earned on...

Speaking to the choir

A friend found the following chart about the "carbon cycle", and sent me an exasperated note, having given up on figuring it out. The chart came from a report, and was reprinted in Ars Technica (link). The problem with the chart is that the designer is speaking to the choir. One must know a lot about the carbon cycle already to make sense of everything that's going on. We see...

Visualizing fertility rates around the globe

The following chart dropped on my Twitter feed. It's an ambitious chart that tries to do a lot. The underlying data set contains fertility rate data from over 200 countries over 20 years. The basic chart form is a column chart that is curled up into a ball. The column chart is given colors that map to continents. All countries are grouped into five continents. The column chart can only...

Charts that ask questions about the German election

In the prior post about Canadian elections, I suggested that designers expand beyond plots of one variable at a time. Today, I look at a project by DataWrapper on the German elections which happened this week. Thanks to long-time blog supporter Antonio for submitting the chart. The following is the centerpiece of Lisa's work: CDU/CSU is Angela Merkel's party, represented by the black color. The chart answers one question only:...

Ridings, polls, elections, O Canada

Stephen Taylor reached out to me about his work to visualize Canadian elections data. I took a look. I appreciate the labor of love behind this project. He led with a streamgraph, which presents a quick overview of relative party strengths over time. I am no Canadian election expert, and I did a bare minimum of research in writing this blog. From this chart, I learn that: the Canadians have...
