I already had a look at Rendering huge amount of points
My situation is, I have huge amount of points (about 1 million). I have to display these points on a map. I searched but I found ArcGIS solutions. I want an open source one.
I started of with Leaflet. In Leaflet, we can cluster the points, but I can't do that, because my points represent a trend on surface of the Earth, and cluster loses that information.
What are my options?
