Python: Use pycha to quickly draw common office charts (seven types of charts, including pie chart, vertical histogram, horizontal histogram, and scatter chart)

This evening I learned how to use the pycha module to create various office charts. This is very simple. In this article, I have used seven charts.

This module and the API address are: Release.

I. Code:
