I am trying to find a fast method to visualize very BIG datasets (up to 1,6 Mio points) as a heatmap with javaScript. I tried to use leaflet-heat.js, but it is extremely slow with such a large number of points. I also tried leaflet-clustering, but on the beginning it is 10x slower as a heatmap and sometimes crashes (once the clusters are built, it is fast).

Any ideas how can a make a heatmap-layer that draws million of points fast?
