Excellent plugin – fully responsive – easy to use

This plugin is easy to learn and use, and has excellent documentation including a helpful video.
It makes it simple to take an image and draw clickable areas on it. In my case the image was a complicated map with lots of oddly shaped clickable areas. But the image could be anything.
Most importantly the resulting page is fully responsive, so the clickable areas work correctly on a tablet or phone as well as on a computer.
