Scales of Analysis
National: This map displays Covid cases in specifically China. It shows more details than the global scale map because it's on a national scale which is smaller.
Local: This is a local scale map of Shanghai which displays how it was split by lockdown in an attempt to control Covid cases. It shows much more details of a smaller scale area than any of the other maps.
Regional: This map displays life expectancy throughout the continent of Asia. China is displayed towards the east with a life expectancy of 77.4 years. It displays less data than a national or local scale map because it doesn't show data in provinces in China, just China as a whole.
Global: This is a global scale map. You can see China on the East of the map, it doesn't show it in much detail because of how large-scale the map is. It just shows how many Covid cases China has as a whole, instead of individual provinces/areas in China.
