Yields Heatmap Lens 1.0.0

Yields Heatmap Lens

This mod contains a suite of lenses for the built tile's yield to display its output in 5-level of shades like a heatmap.
This output is normalized for individual player so its "heat" is relative to the individual player and not the total value.

In the example screenshots attached with this mod, you can see an example of Gao's city centre being the main source of Happiness and Culture production for Hatshepsut's civilization. Himiko's Ba'ak, on the other hand, are a little more distributed.
This is strictly for displaying yields from tiles so it may not be very effective for some yields such as Influence.
