Graph Shapes is a guided tour of how key patterns show up in data and models—from math and physics to engineering, computing, economics, and UX research. The page connects curve families (parabolic, hyperbolic, sinusoidal, logarithmic) with geometric and network structures (polygons, convex hulls, triangulations, trees, planar embeddings). It then expands into common chart forms like line trends, scatter correlations, and histogram distributions, showing what each shape suggests for interpretation.
