I’m using the blueprint of a house, inside the parts of the house, have sensors. I want to make a heat map, mapping the places where most sensors fire, but I don’t know where to start. I’m trying to do some CSS scams, but from what I researched, it uses Javascript, only I’m still lost in it

  • Rephrase your question being more objective, we don’t know if you want to build an application that generates a heat map for any picture inserted or just edit an image.

  • What do you think of making a contactor of each sensor in the house, there will have the amount, can use this amount to darken the color, can do this via javascript, search on. Now Voce will have a sensor at each point of your plant defined in your css by id, via javascript Voce can handle this.

There are several ways to implement a heatmap. If you want to use something already ready, 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 can be useful to you.
