This example demonstrates how to use a radial_bar_chart with a radial_bar. The radial_bar_chart takes in data and then the radial_bar takes in a data_key. A radial bar chart is a circular visualization where data categories are represented by bars extending outward from a central point, with the length of each bar proportional to its value.

The start_angle and end_angle define the circular arc over which the bars are distributed, while inner_radius and outer_radius determine the radial extent of the bars from the center.
