What is the best way to implement an interactive building plan?

Question

JavaScript

Good evening friends.
This is the task before me. There is an image of the building (raster). When hovering over a floor, that floor is highlighted. When you click on this selected floor, the floor plan opens (again, a raster). When you hover over a certain apartment, this apartment is highlighted.
What do you think is the best way to solve this problem, and can you recommend it?

Answer 1

Perhaps someone will come in handy. A similar interactive plan with the ability to export to your site can be drawn in the free service genplan.vsfr.ru
