Creating chart with filled gap between lines

I'm trying to create a chart like shown in the image. I've created this in excel, but I'd like to include it in a real-time web dashboard.

The chart contains two separate data streams (stream1 and stream2). I need to create a chart which will paint in green all areas were stream1 has value greater than stream 2, and red when it's lower.

I have the timseries as dataframes in pandas, python.

Could anyone suggest the best/easiest way I could create such a chart?

Thank you.
