Graphica turns abstract graph theory into something you can actually see. Build your own graphs or load sample ones, then watch nine classic algorithms run step by step — from breadth-first and depth-first search to Dijkstra's shortest path and minimum spanning tree algorithms like Kruskal's and Prim's. FEATURES • 9 graph algorithms, visualized step by step • Pinch-to-zoom canvas for graphs of any size • Synchronized pseudocode panel — see exactly which line is executing • Ready-made sample graphs to explore immediately • Build and edit your own custom graphs • Fully native SwiftUI, built for iOS PRIVACY FIRST Graphica works completely offline. No account, no ads, no analytics, no tracking — your data never leaves your device. Whether you're a computer science student preparing for exams, a developer brushing up before technical interviews, or simply curious how these algorithms work, Graphica makes graph theory click.
