The novel coronavirus is dominating Twitter chatter among the global data journalism community this week. Our NodeXL #ddj mapping from March 9 to 15 finds The Washington Post simulating social distancing scenarios and their effects on slowing the spread of COVID-19, the South China Morning Post highlighting research into a cluster case, Süddeutsche Zeitung charting exponential growth in countries with high infection rates, and The New York Times spotlighting jobs that put workers at greatest risk of contracting the virus.

How to Slow the Spread of COVID-19

This Washington Post piece emphasizes the importance of social distancing measures in slowing down the spread of the coronavirus. By using bouncing balls, it simulates what could happen in four movement scenarios: a free-for-all, attempted quarantine, moderate social distancing, and extensive social distancing. The simulations were done with Canvas API and the charts are made in SVG with D3.js.

How COVID-19 Spread in a Bus

According to the South China Morning Post, a group of researchers from Hunan province investigating a COVID-19 cluster case discovered that a bus passenger managed to infect fellow travelers sitting 4.5 meters away. This is further than the official “safe distance” of one to two meters advised by authorities. The article also advocates the wearing of masks for the public, which is at odds with advice by other medical experts about the masks’ effectiveness in prevention of infection.

Flattening the Curve

German daily Süddeutsche Zeitung charted the increase in number of cases in countries with high rates of infection, such as South Korea, Italy, France and Germany, to show a trend of exponential growth in cases, and to emphasize the importance of “flattening the curve” — diminishing the rate at which new cases occur. If the spread of the novel coronavirus is not slowed down with countermeasures, more than a million people in Germany could be infected with the virus by mid-May, they report. More coronavirus-related data stories are listed here. (In German.)

Jobs with Greatest Risk of Exposure

Which jobs put workers at the greatest risk of contracting the coronavirus? The New York Times tried to figure that out by calculating risk levels of various jobs using O*NET, a database maintained by the Department of Labor that describes various physical aspects of different occupations. Hint: it’s not a great time to be a dentist or paramedic.

Trump Cherry-Picking Charts

Alberto Cairo, Knight Chair in Visual Journalism at the University of Miami, blogs about how US President Donald Trump conveniently cherry-picked statistics to suggest that stock markets experienced a rapid recovery after his press conference on the coronavirus. Cairo explains how the chart shown by Trump is misleading and only a small part of the big picture.

Lost Parts of Berlin

The historic city of Berlin-Cölln used to hold more than 1,200 buildings, but most of them were demolished or bombed. Only 85 remain. On the occasion of the hundredth birthday of Greater Berlin, Der Tagesspiegel dug into map archives to compare the current Berlin to the old city before the Second World War.
