Hello, I'd like a map with hexagons that are darker the more points there are underneath. My points are in a PostgreSQL table. If there are no points, there should be no hexagon. The hexagons have a constant size on the screen, so they have to be recalculated each time the map is zoomed in. I want a truly optimized solution because I have millions of points. So, perhaps I could use QGIS-server. Please suggest a solution for both the server and client side. Best regards PS : my map must be like GBIF maps
