Here are a couple of map layer maps on top of Google Maps, using a GeoJSON source based on the OpenSourceMap charging point information.
Circle size is the power of the most powerful charger at a location. Color is the operator. Hover over shows you the main info on the top one and click on the bottom one.
It's nice because Google maps is fast, and is also fast, and GeoJSON is easy to use.

Takes a few seconds to load the data the first time.
