How to create a Heat Map

Hi Everyone,
I have temperature values that come from the sensors, I created the sensors in Revit and I connected the temperature values to them.
For an intuitive visualization in Revit I created a Color Range on the sensors.

Now I would like to create a heat map on the total surface, based on the position and temperature value of the sensors but I don’t know how to proceed.
If anyone can give me advice I would be really grateful!
