Generating heatmap layer for milions of points : <p>I'm using heatmap layer from Google Maps to display a heatmap, however, I now have too many points and it stopped working, because browser cannot handle it anymore. I've found that they provide Fusion Tables, but they're also limited: to 100k rows, which is way too low. I need to render heatmap of milions or maybe even more points. I'd be perfect if my server can have some PHP script to render a heatmap, for example, once a day. And then a client from js will just download a preloaded heatmap (on the map like google maps, but may be different map too). Is this possible with some existing technology (can be commercial)?</p>
