Graph Drawing with Intelligent Placement (GRIP) // Implements the GRIP multiscale graph layout workflow for ordinary graphs and a geometry-aware weighted GRIP workflow for weighted graphs in 2D and 3D. Provides layout scoring, candidate comparison, multiscale trace diagnostics, synthetic graph families, and advanced experimental geodesic-KK utilities for weighted-layout evaluation and polish.
