Case rates adjusted for the unvaccinated

Covid-19 cases in the United States were down, but they’re moving up again, mostly among the unvaccinated. Dan Keating and Leslie Shapiro for The Washington Post break down the comparisons by state. A difference chart for each state shows the overall rate compared against an adjusted rate for the unvaccinated population. As you might expect, the rate for the latter is always higher. There are three more points of reference....

Falling spin rates in baseball after rule enforcement

NYT’s The Upshot analyzed spin rate on pitches before and after enforcing a ban on sticky substances that provide more grip on the ball. The rule has been in place for decades but wasn’t enforced. However, there’s been more strikeouts than usual, which makes for less exciting sports, which means less people watch, and therefore, the league makes less money. So, bye sticky stuff.

Slowing and then renewed interest in getting vaccinated

When countries gained access to vaccines, there was an initial burst of vaccinations, but the rate leveled off in most places. Then a variant arrives, and an incentive or another push for vaccinations increases the rate. Reuters looks at the rate shift in different countries, in the context of trying to reach 70 percent vaccinated. The set of difference charts took me a minute to digest, but then seems straightforward...

How sports owners pay less taxes than athletes

ProPublica continues their analysis of an anonymous dump of tax records, this time with a focus on billionaire sports owners: The law favors people who are rich because they own things over people who are rich because they make a high income from their work. Wages — the main source of income for most people, including athletes — are taxed at the highest rates of all, topping out at a...

All the matches from Euro 2020 in one chart

To see all the matches from the group stage of Euro 2020 in one chart, Krist Wongsuphasawat used a streamgraph showing aggregate scorelines from kickoff to finish. All matches start at 0-0, and the team that scores first, colored in blue, almost always wins. The percentage of comeback wins surprises me, as someone who knows almost nothing about soccer.

Scoring hospitals by billing quality

Using data collected by Johns Hopkins University, Michelle McGhee and Will Chase for Axios provide a visual reference for the billing practices of for-profit hospitals: Rising deductibles and out-of-pocket costs are increasingly leaving patients responsible for bloated medical bills. A new analysis by Johns Hopkins University reveals that many of the top 100 hospitals by revenue in the U.S. use predatory tactics to pursue patients with unpaid bills. Tags: Axios,...

India vaccine procurement compared to other countries

Prasanta Kumar Dutta and Manas Mishra reporting for Reuters on the slow rollout of Covid-19 vaccinations in India: Compared to many Western countries, India was late in procuring vaccines. Modi’s government placed the first advance order for an unapproved vaccine only this month, after being criticised for being slow. Countries including the United States and Britain signed orders last year. Tags: coronavirus, India, Reuters, vaccine

Graphs before anyone knew what they were

Michael Friendly and Howard Wainer have a new book out: A History of Data Visualization and Graphic Communication. They rewind back 400 years and discuss the beginnings of visualization, when nobody knew what a chart was. Putting this in my queue and hoping it’s back in stock soon. Visualization still seems like a relatively new thing. It’s old. Tags: book, history, Howard Wainer, Michael Friendly, New Yorker

All the passes in soccer visualized at once

This is a fun soccer graphic by Karim Douïeb. It shows 882,536 passes from 890 matches across various leagues and seasons. It looks cool as a static point cloud, but be sure to check out the animated, interactive version which lets you isolate the view to specific parts of the field. It reminds me of the Windows 3.1 fireworks screensaver. Those were the days. You can find the data via...
