Hi.

I'd like to know if it's possible to make a heatmap panel which would visualize 2D point data on an image depending on some other query's result. For example, I'm sending now all touch points to logstash in the form of (url, x, y) where url is current "page" in my application. So, I thought it would be cool to make such visualization right in Kibana.

I'm still googling, found couple JS libraries and tons of other code. Has anyone built such functionality already?
