Coronavirus Region Comparison

This website allows you to compare the progression of COVID-19 between different regions, including countries and state of the United States of America. The graph shows data starting from when that region had 100 confirmed cases of COVID-19. This means the progression of each region can be compared next to each other. Different types of data can be graphed simultaneously, such as the confirmed cases, deaths, an CFR. The Johns Hopkins and European Centers of Disease Control datasets are listed. The data is updated once per day.

Frequently Asked Questions

Why are some points larger than others?

Weekend days are given a larger point size in order to make the weeks stand out.

Why don't some data points show up?

There are a few reasons for this:

  1. ECDC does not have recovered data and it does not have USA state data.
  2. At most, 12 lines can be plotted at a time. Try removing some values or regions.

Is the data manipulated in any way?

Yes, in a few ways. The JHU CSSE data contains information either per region or per province within a region. In the case where there is data per province, there is not aggreated data for that region, so the transformation script performs the aggregation. Additionally, if there is no data point for a region for a particular day, that day is set to 0 so it can still be graphed. This is why some regions have a CFR for recovered at 100%. Usually that means there is no recovered data point for that day.

Additionally, region names are not always consistent in the data. A mapping has been added to the transform script to put those regions under a single name. For example, in some cases South Korea is referred to as "Korea, South" and in other cases "South Korea". The transformation script maps "Korea, South" to "South Korea" so it is consistent. Similarly, "Hong Kong" and "China (Hong Kong)" are both in the data. It appears that originally the values were named "Hong Kong" but at some point the naming switched to "Hong Kong" province with "China" as the region. "Hong Kong" is mapped to "China (Hong Kong)".

What specific data is used?

The daily reports located in the csse_covid_19_data/csse_covid_19_daily_reports/ directory.

How frequently is the data updated?

The JHU CSSE data directory used is updated once per day and it is currently imported sometime in th morning UTC.

What is used to visualize the data?

This visualization is powered by Chart.js.
