Detect Diagram Crossings

Purpose

Provide a rigorous, multi-method approach to detecting edge crossings and overlaps in SVG flowchart diagrams. This skill combines mathematical geometric analysis with visual inspection to ensure diagrams have clean, crossing-free layouts.

When to Use

• Validating Diagram Layouts: After creating or modifying workflow diagrams
• Quality Assurance: Before committing diagram changes to ensure no crossings
• Debugging Visual Issues: When users report crossing/overlap problems
• Comparative Analysis: Testing multiple layout versions to find the best one

Detection Methods

Method 1: Parametric Line Intersection (Mathematical)

The primary detection method uses parametric line equations to mathematically determine if two line segments intersect.
