The German Robert-Koch-Institute (RKI) is the legal basis for self-isolation in Germany. If somebody stayed in an international area that is declared as a Covid-19 risk area by the RKI in the last 14 days and arrives to Germany, the person is required to go into quarantine for 2 weeks. However, the RKI only offers its risk area data as a basic text list. I turned this into world map visualization that scrapes the data from the RKI website every hour.
