Use a photo or graphic with color overlays

[#1]

I need to identify workers in a specific company division on a graphic. The graphic is a picture of a division map.  How to I associate/relate the data to a spot or region on the graphic to indicate that region/district/area and/or to pin-drop on a specific location on that graphic?

This is similar to the geo-heat map but using another graphic instead of that map.

any help is truly appreciated.

Thanks!!!!

I need to outline a specific polygon and fill it with color/design and then overlay it on the graphic.
