Draggable background

Dear Sir or Madam,

I would like to build up a background that can be dragged like a Google map and have some hotspots which have different topics to move into. If anyone knows how to build up this kind of draggable map via Javascript or any embedded functions? No need to zoom in or out.

Example 1: https://mapofmetal.com/

Example 2: https://www.google.com/maps

Thanks!
