Features
Force-Directed Tree Layout
A physics‑based layout algorithm that automatically positions nodes using virtual springs and electrical repulsion forces. This reduces edge crossings and visual clutter, producing cleaner and more intuitive layouts for complex tree structures and irregular hierarchies.
- AttractionStrength – Controls the force that pulls connected nodes toward their ideal separation distance.
- RepulsionStrength – Controls the force that pushes nodes apart to prevent overlap and maintain clear spacing.
- MaximumIteration – Specifies how many simulation steps the algorithm runs to position nodes, or until movement stabilizes and equilibrium is reached.
