Explains or Magnify parts of an image on hover in a modal like fashion

Hi, does anyone know of a plugin or steps to take to learn such?

For example, there are "circles" highlighting parts of a toy, and when hovered, it would have a modal come out showing a different image with captions, something like a flash.

Or in another case, a small scale map with circles on different location will display a house or a land, when hovered.

Thanks.
