 - Jun 2026: Added interactive Graph Traversal (BFS / DFS) built on React Flow
 - Jun 2026: Added Shortest Path (Dijkstra / Bellman-Ford) and Minimum Spanning Tree (Kruskal / Prim) on a shared, reusable graph workspace
 - Jun 2026: Added Connectivity (components / SCC / WCC) and Network Flow (Edmonds-Karp / Ford-Fulkerson, max flow / min cut)
+- Jun 2026: Added a reusable SVG tree component with a Binary Search Tree visualizer, and migrated the Recursion Tree onto it
