DHIS 2 is the flexible, web-based open-source information system with awesome visualization features including GIS, charts and pivot tables.
A new open source DHIS2 service with the new COVID-19 module is being set up in Norway for local and regional authorities. Developed at the University of Oslo with funding from WHO, the DHIS2 service and app has been deployed to 60+ countries. Maybe something for your country too?
