Foodies say, add dataviz spice please

This Buzzfeed article proves that foodies love their food served with dataviz (tip: Chris P.). Menus are an undertapped resource when it comes to data visualization. There are several examples worth discussing. Venn diagrams are not easy to read, people. Plus they are hard to construct well... note the asymmetric areas. Here is one without circles: Then, I pared it down to its essence: *** This beer map is pretty...

A gem among the snowpack of Olympics data journalism

It's not often I come across a piece of data journalism that pleases me so much. Here it is, the "Happy 700" article by Washington Post is amazing.   When data journalism and dataviz are done right, the designers have made good decisions. Here are some of the key elements that make this article work: (1) Unique The topic is timely but timeliness heightens both the demand and supply of...

A chart Hans Rosling would have loved

I came across this chart from the OurWorldinData website, and this one would make the late Hans Rosling very happy. If you went to Professor Rosling's talk, he was bitter that the amazing gains in public health, worldwide (but particularly in less developed nations) during the last few decades have been little noticed.

There are two related metrics to describe the durability of the stash,...

Three pies and a bar: serving visual goodness

If you are not sick of the Washington Post article about friends (not) letting friends join the other party, allow me to write yet another post on, gasp, that pie chart. And sorry to have kept reader Daniel L. waiting, as he pointed out, when submitting this chart to me, that he had tremendous difficulty understanding it:   This is not one pie but six pies on a platter. There...

Mapping the two Americas

If you type "two Americas map" into Google image search, you get the following top results: Designers overwhelmingly pick the choropleth map as the way to depitct the two nations. Now, look at these maps from the New York Times (link): and this: I believe the background is a relief map. Would like to see one where the color is based on the strength of support for Democrats or Republicans....

Here are the cool graphics from the election

There were some very nice graphics work published during the last few days of the U.S. presidential election. Let me tell you why I like the following four charts. FiveThirtyEight's snake chart This chart definitely hits the Trifecta. It is narrowly focused on the pivotal questions of election night: which candidate is leading? if current projections hold, which candidate would win? how is the margin of victory? The chart is...

Dot plots are under-valued, that’s all

Bar charts are over-used and over-rated. Just casually, I found this example at US News: Are you comparing bar widths? Or the printed data? Here is a dot plot:
