I have been trying to find a way to create 3D bars on top of google map along the lines of a road representing some parameters related to road condition.
I m trying to achieve something like this but on google maps instead.
I tried to look for available charting libraries. The closest one I could get to is Mapbox , using the hexbins 
However, it is not flexible enough to include my own user interactions and control.
Another impressive demo that I came across is this from Xibis. However it is just a sample and I couldn't figure out how it is done.
Are there any such libraries available or any ideas to achieve something similar?
