generate_polar_chart

Create polar charts (rose, radar, pie) to visualize numerical differences across categories using polar coordinates, with customizable dimensions, themes, and axis settings.

Instructions

Generate a polar chart (rose, radar, pie) to display numerical differences among different categories using radius and angle in polar coordinates.
