I stumbled across this issue today. It's the result of a slight typo in the pygal config file.

Fortunately it's simple to fix. Open the config.py file in the pygal directory and add http to the kozea github url as follows:

    js = Key(

as a parameter to your rendering function, e.g.

chart.render_to_file(output_file, force_uri_protocol='https')
