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.
