Seeking Plugin Advice for Image Mouseover Text Points

Hello -

I'm wondering if anyone knows a plugin that will allow me to place "points" or small indicators on different places of an image so that when a user points to that spot, text explanation appears. Image attached.

This plugin (link below) will do it, but it only works with their "Builder" product, and their builder causes issues with our theme. Plus I would just like a more streamlined approach than piling on two plugins to an already plug-in heavy WordPress installation.

Thanks for any help or insight!
