Radial Column Chart

Radial column charts display data as columns radiating from a central point on a polar coordinate system. They are particularly effective for directional data like wind patterns or time-based metrics where the circular nature emphasizes periodicity.

"Create a radial column chart (wind rose) displaying 'Wind Speed Distribution' by direction for a coastal weather station. Generate realistic wind data for 16 compass directions (N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW, NNW). For each direction, show percentage of observations (total 100%) with prevailing winds from SW (15%), W (18%), NW (12%). Color columns by average wind speed in that direction using a blue-to-red gradient (5-25 mph range). Add concentric rings at 5%, 10%, 15%, 20% frequency. Include cardinal direction labels (N, E, S, W) and intermediate labels. Add legend for wind speed. Title: 'Annual Wind Rose - Coastal Station'."
