This change adds a new wind rose chart operator, which visualizes how a magnitude (radial value) is distributed across different directions (angular values) and optionally grouped by a categorical variable (color).
In a wind rose chart:
- Each angular segment represents a direction (e.g., N, NE, E).
- The length of each bar from the center represents the magnitude or frequency for that direction.
- Color can optionally represent an additional grouping variable, such as strength or category.
This visualization is useful for understanding directional distributions, identifying dominant directions, and comparing patterns across different groups or conditions. The operator takes in 2 or 3 inputs: the radial values, the angular values, and optionally a color/grouping variable
