please help I cannot seem to get the json data into a Dataframe.

loaded the data data =json.load(open(r'path'))#this works fine and displays:

You can further add record field in the normalize method to create more columns for the polygon coordinates.

You can find more documentation at https://pandas.pydata.org/pandas-docs/version/1.2.0/reference/api/pandas.json_normalize.html

Hope that helps.
