Graphy - LeetCode Graph Visualizer

LeetCode Graph Visualizer: turn test cases into trees, linked lists, grids, and graphs, then watch your solution run step by step.

Graphy is a LeetCode graph visualizer that turns LeetCode test cases into interactive diagrams of binary trees, linked lists, and graphs. Instead of reading raw arrays, you see the data structure drawn out, and you can draw your own custom test cases too. When you run your solution, Graphy visualizes the algorithm step by step on the graph, showing the current node, visited nodes, and the BFS or DFS frontier, so you can understand and debug tree, linked list, and graph problems faster. What's new in 2.0.0: • New Structures ◦ N-ary trees, Random point lists, Grids up to 2,500 cells • Faster, More Accurate Tracing • Redesigned Style drawer ◦ Auto theme that follows LeetCode's light or dark mode ◦ Recent images, drag and drop, and a new color picker • Better LeetCode integration ◦ Testcase edits show up live ◦ The panel opens only on problems Graphy can draw ◦ Contest problems are supported • Other ◦ leetcode.cn is no longer supported ◦ Bug fixes and optimizations
