As the current epidemic takes over Europe, one of the major effects has been the reduction of air traffic. Craig Taylor, a data visualization specialist has captured this well in a couple of tweets showing the differences across Europe over the past two weeks. The first one is a little harder to read but in the second one you can really see the dropoff in flights by the height and number of blue bars - as opposed to red ones.
So to quantify the difference I binned all positions recorded into a grid over Europe. Pivot each grid to find totals and compare the days. 🔵 Higher count on 10th 🟠 Higher count on 24th #dataviz #map pic.twitter.com/OHnYnztJmo— Craig Taylor (@CraigTaylorViz) March 25, 2020
