javascript – Is it possible to make a HEAT MAP on an image?

Question:

I'm using a house plan, inside the house parts, they have sensors. I want to make a heat map, mapping the places where the sensors fire the most, but I don't know where to start. I'm trying to do some workarounds with CSS, but from what I've researched, it uses JavaScript, but I'm still lost in it

Answer:

There are several ways to implement a heatmap . In case you want to use something ready-made, Heatmap.js is a javascript library that does just that. According to its documentation, the library supports up to 40,000 points per map.

This is an example that you may find useful .
