How to add simple imagemaps with hotspots for propert panos

I am a beginner and struggling to add simple plans with hot spots for each room for property panos to my skin.

The two examples: scenes-with-imagemap & scenes-with-imagemap2, radar which seems to complicate things.......

Could someone please send an example of a simple code that I could use as a basis for a a house plan with hotspots.

Thank you
