Build a Custmized Data Visulization Tool with Bokeh (Python project)

The requirement is to build a data visulization tool with Python (mainly Pandas and Bokeh); it should have the interactive function listed in the word file: to specify data for x-value, y-value, graph type, graph color, and update chart with JavaScript(this can be done with the CustomJS in Bokeh).
The final project can be a single python file or a flask project.

I have a python file which contains the feature required, for your reference; I will provide the file later.
