The infection data about all the counties of Estonia in comparison to other counties. This visualization was created by the research group from the University of Tartu and was published early April to share information with the public.
This was very important because there were three countiesthat were very heavily infected.

Testing data visualized county by county to inform the public which areas are more infected. This visualization also allows politicians to make better decisions, e.g Saaremaa was heavily infected and it was obvious they needed more federal help, so a military hospital was opened there.
