The rule governing which variable to put on which axis, served a la mode

When making a scatter plot, the two variables should not be placed arbitrarily. There is a rule governing this: the outcome variable should be shown on the vertical axis (also called y-axis), and the explanatory variable on the horizontal (or x-) axis. This chart from the archives of the Economist has this reversed: The title of the accompanying article is "Ice Cream and IQ"... In a Trifecta Checkup (link), it's...

Form and function: when academia takes on weed

I have a longer article on the sister blog about the research design of a study claiming 420 "cannabis" Day caused more road accident fatalities (link). The blog also has a discussion of the graphics used to present the analysis, which I'm excerpting here for dataviz fans. The original chart looks like this: The question being asked is whether April 20 is a special day when viewed against the backdrop...

A data graphic that solves a consumer problem

Saw this great little sign at Ippudo, the ramen shop, the other day: It's a great example of highly effective data visualization. The names on the board are sake brands.  The menu (a version of a data table) is the conventional way of displaying this information. The Question Customers are selecting a sake. They don't have a favorite, or don't recognize many of these brands. They know a bit about...

Not following direction or order, the dieticians complain

At first glance, this graphic's message seems clear: what proportion of Americans are exceeding or lagging guidelines for consumption of different food groups. Blue for exceeding; orange for lagging. The stacked bars are lined up at the central divider - the point of meeting recommended volumes - to make it easy to compare relative proportions. The original chart is here, on the Health.gov website. The little icons illustrating the food...

Happy New Year

In China, 2019 is the Year of the Pig. Half of the world's pigs live in China. This graphic is inspired by this BouncyMaps project, which generated the following cartogram.

Made in France stereotypes

Kaiser Fung (JunkCharts, Principal Analytics Prep) shows how to use the Trifecta Checkup to identify weaknesses in data visualization, and also how to conceptualize good charts using the same framework. He uses an example inspired by a Made in France poster.

Made in France stereotypes

France is on my mind lately, as I prepare to bring my dataviz seminar to Lyon in a couple of weeks.  (You can still register for the free seminar here.) The following Made in France poster brings out all the stereotypes of the French. (You can download the original PDF here.) It's a sankey diagram with so many flows that it screams "it's complicated!" This is an example of a...

Big Macs in Switzerland are amazing, according to my friend

Note for those in or near Zurich: I'm giving a Keynote Speech tomorrow morning at the Swiss Statistics Meeting (link). Here is the abstract: The best and the worst of data visualization share something in common: these graphics provoke emotions. In this talk, I connect the emotional response of readers of data graphics to the design choices made by their creators. Using a plethora of examples, collected over a dozen...

Some Tufte basics brought to you by your favorite birds

Someone sent me this via Twitter, found on the Data is Beautiful reddit: The chart does not deliver on its promise: It's tough to know which birds like which seeds. The original chart was also provided in the reddit: I can see why someone would want to remake this visualization. Let's just apply some Tufte fixes to it, and see what happens. Our starting point is this: First, consider the...

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...
