public final class BeeswarmRenderer
extends BaseRenderer

BeeswarmRenderer - Beeswarm Plot (Stripchart)

Professional beeswarm plot renderer for showing individual data points without overlap. Each point is positioned to avoid overlapping while maintaining vertical alignment by category.

Features:

• No Overlap: Points are jittered horizontally to avoid collision
• All Data Visible: Every data point is shown individually
• Distribution Shape: Reveals density and outliers
• Category Grouping: Points grouped by category (x-value)

Advantages over:

• Box Plot: Shows all individual points, not just summary statistics
• Violin Plot: More precise, shows exact values
• Scatter with Jitter: Intelligent layout, no random overlap

Use Cases:

• Small to medium datasets (< 500 points per category)
• Comparing distributions across groups
• Identifying outliers and clusters
• Showing all data points transparently
