Description

Describe the solution you'd like
without change the default color in current folium heatmap.
we want to see a color legend can be show on map and different color proportion can be showed next to the color legend.

Describe alternatives you've considered
add a color legend can show the correspondence between clor and value
add a color proportion can tell user the percentage of different color, it is very convenient for making statistics.

Research direction

Start by reviewing folium.heatmap and the linked heat-map example to define the legend and color-proportion requirements without changing the default coloring. Confirm how the requested visualization should appear on a map; done means the map shows the color-to-value correspondence and proportions alongside the legend.
