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.
