"""
=============
Radio Buttons
=============

Using radio buttons to choose properties of your plot.

Radio buttons let you choose between multiple options in a visualization.
In this case, the buttons let the user choose one of the three different sine
waves to be shown in the plot.

Radio buttons may be styled using the *label_props* and *radio_props* parameters, which
each take a dictionary with keys of artist property names and values of lists of
settings with length matching the number of buttons.
