Here's a quick R plot of population in Indian states and the breakdown by the religion people practice. The data was obtained from this Indian government site. I'm looking for other state-level data to overlay on this to find interesting patterns e.g. crime, literacy etc.
Here's the demographics of India on Wikipedia.
As next steps, I would like to:
1) "zoom" into the areas of chart that are too small to be interpreted properly, and
2) plot this data on the map of India.
