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

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.
How to do it...

from_counts = np.load("from_counts.npy")
