Heat map (GeoHash) on Geo Map


I would like to visualise KPI on the geo map as an example below. We can prepare coordinates for grid but how it can be visualise on Arcadia map. Is it possible or special setting required.
Please advise. Thank you very much.


@Stima_Livingpresent we do not allow grids, but you can use the bubble setting of the map visual to display gradients. See below:
