Graphing the economic crisis of Covid-19

My friend Ray Vella at The Conference Board has a few charts up on their coronavirus website. TCB is a trusted advisor and consultant to large businesses and thus is a good place to learn how the business community is thinking about this crisis. I particularly like the following chart: This puts the turmoil in the stock market in perspective. We are roughly tracking the decline of the Great Recession...

Food coma and self-sufficiency in dataviz

The Hustle wrote a strong analysis of the business of buffets. If you've read my analysis of Groupon's business model in Numbersense (link), you'll find some similarities. A key is to not think of every customer as an average customer; there are segments of customers who behave differently, and creating a proper mix of different types of customers is the management's challenge. I will make further comments on the statistics...

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...

Taking small steps to bring out the message

Happy new year! Good luck and best wishes! *** We'll start 2020 with something lighter. On a recent flight, I saw a chart in The Economist that shows the proportion of operating income derived from overseas markets by major grocery chains - the headline said that some of these chains are withdrawing from international markets. The designer used one color for each grocery chain, and two shades within each color....

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

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...
