Consumption patterns during the pandemic

The impact of Covid-19 on the economy is sharp and sudden, which makes for some dramatic data visualization. I enjoy reading the set of charts showing consumer spending in different categories in the U.S., courtesy of Visual Capitalist. The designer did a nice job cleaning up the data and building a sequential story line. The spending are grouped by categories such as restaurants and travel, and then sub-categories such as...

Hope and reality in one Georgia chart

Over the weekend, Georgia's State Health Department agitated a lot of people when it published the following chart: (This might have appeared a week ago as the last date on the chart is May 9 and the title refers to "past 15 days".) They could have avoided the embarrassment if they had read my article at DataJournalism.com (link). In that article, I lay out a set of the "unspoken conventions,"...

How the pandemic affected employment of men and women

In the last post, I looked at the overall employment situation in the U.S. Here is the trend of the "official" unemployment rate since 1990. I was talking about the missing 100 million. These are people who are neither employed nor unemployed in the eyes of the Bureau of Labor Statistics (BLS). They are simply unrepresented in the numbers shown in the chart above. This group is visualized in my...

How Covid-19 deaths sneaked into Florida’s statistics

Like many others, some Floridians are questioning their state's Covid statistics. It's clear there are numerous "degrees of freedom" for politicians to manipulate the numbers. What's not clear is who's influencing these decisions. Are they public-health experts, donors, voters, or whom? A Twitter follower sent in the following chart, embedded in an informative article in Sun-Sentinel: I like the visual design. It's clean, and conveys a moderately complex concept effectively....

Twitter people UpSet with that Covid symptoms diagram

Been busy with an exciting project, which I might talk about one day. But I promised some people I'll follow up on Covid symptoms data visualization, so here it is. After I posted about the Venn diagram used to depict self-reported Covid-19 symptoms by users of the Covid Symptom Tracker app (reported by Nature), Xan and a few others alerted me to Twitter discussion about alternative visualizations that people have...

This exercise plan for your lock-down work-out is inspired by Venn

A twitter follower did not appeciate this chart from Nature showing the collection of flu-like symptoms that people reported they have to an UK tracking app.  It's a super-complicated Venn diagram. I have written about this type of chart before (see here); it appears to be somewhat popular in the medicine/biology field. A Venn diagram is not a data visualization because it doesn't plot the data. Notice that the different...

Graphing the extreme

The Covid-19 pandemic has brought about extremes. So many events have never happened before. I doubt The Conference Board has previously seen the collapse of confidence in the economy by CEOs. Here is their graphic showing this extreme event: To appreciate this effort, you have to see the complexity of the underlying data. There is a CEO Confidence Measure. The measure has three components. Each component is scored on a...

Reviewing the charts in the Oxford Covid-19 study

On my sister (book) blog, I published a mega-post that examines the Oxford study that was cited two weeks ago as a counterpoint to the "doomsday" Imperial College model. These studies bring attention to the art of statistical modeling, and those six posts together are designed to give you a primer, and you don't need math to get a feel. One aspect that didn't make it to the mega-post is...

The hidden bad assumption behind most dual-axis time-series charts

DC sent me the following chart over Twitter. It supposedly showcases one sector that has bucked the economic collapse, and has conversely been boosted by the stay-at-home orders around the world. At first glance, I was drawn to the yellow line and the axis title on the right side. I understood the line to depict the growth rate in traffic "vs a normal day". The trend is clear as day....

An exposed seam in the crystal ball of coronavirus recovery

One of the questions being asked by the business community is when the economy will recover and how. The Conference Board has offered their outlook in this new article. (This link takes you to the collection of Covid-19 related graphics. You have to find the right one from the carousel. I can't seem to find the direct link to that page.) This chart summarizes their viewpoint: They considered three scenarios,...
