I'm trying to create 3D bars on this map. Can anyone please advise if this is possible, and how?
http://leafletjs.com/examples/choropleth.html
My data: UFO sightings in the USA (location wise). Count of these sightings per location will be the height of the 3D bar. Base map is a choropleth with US population density values.
I don't mind integrating Javascript or d3.js into the code to create the 3D bars.
