Indian-Union-Territories-and-States-JSON
I was working on a project and couldn't find a file having the coordinates of all the Indian Union Territories and the States including Telangana in a JSON file format so I decided to make my own.
Download the states.json and feel free to use it in a way it benefits you.
SIDENOTE: To actually plot it on a map, you could use any of the external libraries which provides the user to input an external JSON file.
