Aggregation

Labels, scales, controls, aggregation all in play

JB @barclaysdevries sent me the following BBC production over Twitter. He was not amused. This chart pushes a number of my hot buttons. First, I like to assume that readers don't need to be taught that 2007 and 2018 are examples of "Year". Second, starting an area chart away from zero is equally as bad as starting a bar chart not at zero! The area is distorted and does not...

Men and women faced different experiences in the labor market

Last week, I showed how the aggregate statistics, unemployment rate, masked some unusual trends in the labor market in the U.S. Despite the unemployment rate in 2018 being equal, and even a little below, that in 2000, the peak of the last tech boom, there are now significantly more people "not in the labor force," and these people are not counted in the unemployment rate statistic. The analysis focuses on...

A second take on the rural-urban election chart

Yesterday, I looked at the following pictograms used by Business Insider in an article about the rural-urban divide in American politics: The layout of this diagram suggests that the comparison of 2010 to 2018 is a key purpose. The following alternate directly plots the change between 2010 and 2018, reducing the number of plots from 4 to 2. The 2018 results are emphasized. Then, for each party, there can be...

Crazy rich Asians inspire some rich graphics

On the occasion of the hit movie Crazy Rich Asians, the New York Times did a very nice report on Asian immigration in the U.S. The first two graphics will be of great interest to those who have attended my free dataviz seminar (coming to Lyon, France in October, by the way. Register here.), as it deals with a related issue. The first chart shows an income gap widening between...

Crazy rich Asians inspire some rich graphics

Kaiser Fung (Junkcharts, Principal Analytics Prep) examines several charts made by New York Times on income distribution among Asian Americans, as the hit movie Crazy Rich Asians dominates the U.S. box office in September.

Digital revolution in China: two visual takes

The following map accompanied an article in the Economist about China's drive to create a "digital silkroad," roughly defined as making a Silicon Valley.  The two variables plotted are the wealth of each province (measured by GDP per capita) and the level of Internet penetration. The designer made the following choices: GDP per capita is presented with less precision than Internet penetration. The former is grouped into five large categories...

Fantastic visual, but the Google data need some pre-processing

Another entry in the Google Newslab data visualization project that caught my eye is the "How to Fix It" project, illustrating search queries across the world that asks "how." The project web page is here. The centerpiece of the project is an interactive graphic showing queries related to how to fix home appliances. Here is what it looks like in France (It's always instructive to think about how they would...

Discoloring the chart to re-discover its plot

Today's chart comes from Pew Research Center, and the big question is why the colors? The data show the age distributions of people who believe different religions. It's a stacked bar chart, in which the ages have been grouped into the young (under 15), the old (60 plus) and everyone else. Five religions are afforded their own bars while "folk" religions are grouped as one, and so have "other" religions....

A look at how the New York Times readers look at the others

The above chart, when it was unveiled at the end of November last year, got some mileage on my Twitter feed so it got some attention. A reader, Eric N., didn't like it at all, and I think he has a point. Here are several debatable design decisions. The chart uses an inverted axis. A tax cut (negative growth) is shown on the right while a tax increase is shown...

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...
