This chart shows 2 interesting things. One, Finland was pretty happy under lock down. Two, an interesting way to put data labels on a stacked column chart. The small boxes are always a problem in a regular format. Here you get the combination of the visual effect of the size of the boxes, versus the table of the actual information. This could be inspiration for a future SlideMagic expansion.
I would do some things different though. That row of zeros at the top does not add much. The flags make the whole chart even more busy. And given that this is a comparison, I would have shown the data as a stacked bar chart.
If you were to use me as a bespoke designer, I would actually show this data on a map of Europe, color-coding different countries with maybe only the some of the 2 blue data series. The geographical clustering of the countries is interesting. In addition, I would combine it with one stat about the health impact of COVID in these countries.
If you do not have the software and/or the time to make a chart like this, the solution is easy, take off the data labels completely and make a straightforward stacked column chart.
I found this chart on Twitter, without quoting a source, the format looks like a page in some document by the European Union though.
