Custom Clickable Image I've been using Craft CMS for a while, but haven't seen any way to get the following done:

Looking to create a page with a large image on it. The image would be overlayed with buttons that pop-out a text box or overlaid image. I'd like to place the pop-out boxes/graphics all over the image in specific places, but the creation interfaces I've seen only let me put one image after another in a list, or rectilinear fashion. 
I'm hoping to create a map of a neighborhood where clicking on different buildings/elements pops out another window with more information regarding that area/element.

I hope this is understandable, if more clarity is needed please let me know.

Any insight would be greatly appreciated.

Thanks
Whilst this mainly seems like a front-end development question, and Dr_Codswallop has perfectly summed up some steps in the comments to tackle that, as an answer for the Craft CMS specific side of the question there is a plugin I have used in the past that is very helpful, but it is only for Craft 2.x:

Donkeytail

I have had a look through the plugin store and I can't find an alternative plugin for Craft 3.x, so it looks like you will need to follow Dr_Codswallops instructions and build up something manually if you are running this version of Craft.
