You can use CSS to overlay bernie

There's no need to do any computation server-side to overlay bernie, or use numpy/cv etc.

A CSS stylesheet can overlay the bernie.png image directly on top of a div that holds the result from google maps. I'll work on a PR on this in the evening if no one else gets to it.

I think it's good that it's composited as an image. It can be downloaded.

Agree with @baffalop, it's better server-side.

Agreed, lets keep the images.
