While it is certainly true that some data domains might routinely rely more heavily on particular charts than other domains, that difference does not constitute a separate branch of data visualization. Two prominent reasons for this are 1) the fact that most cases are mild to moderate and therefore never involve the medical intervention, and 2) the fact that many people who would like to be tested cannot because tests are still not readily available.

The article is a response to the recent Axios interview with Donald Trump by Jonathan Swan, which aired on August 3, 2020 on HBO. It indicates the proportional rather than the overall disease burden.

As COVID-19 spreads its deadly effects around the world, many data analysts are struggling to track these effects in useful ways. Here’s the same daily values as before with one additional day, April 6th, included at the end. We can all hope that expert projections that the curve will flatten out in the next few days will come to pass, but we should not draw that conclusion from the newly reported case count for any particular day. If you’ve developed expertise in data visualization while working in finance and you suddenly take a job working in healthcare, you will need to learn about healthcare, but not anything new about data visualization that is unique to that domain.

A great deal of social science and survey-based performance reporting (e.g., customer satisfaction surveys) is based on quantified Likert scales. Ordinal scales often provide meaningful and useful ways to arrange items in a list. I wish we could, but we dare not, for several reasons. The charts that were included in an NPR article titled “Charts: How the U.S. Both sentences above exhibit problems.

Obviously, if we want to compare the patterns of change among these countries more easily, regardless of magnitude, we must solve this scaling problem. Mostly, for convenience. limited in length, scope, or development to require the larger venue.

There are several ways in which COVID-19 deaths per country can be compared, and per capita deaths is one of the most useful.
