| |
| 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. |
