Present a user-interactive graphic using Python

In this section, we use another Python library, bokeh, to display a chart where the user can adjust parameters of the graphic for different results.

Note

The installation instructions for the bokeh library are very complex. Again, they're specific to the operating system and version of Python you are using in your installation.

We are presenting online voter information, with the data points showing, for each user ID, how many votes they received for some post they made.
