  "summary": "Understanding code execution, call stacks, and pointer mutations can be tricky—especially when debugging complex algorithms, recursion, or data structures like linked lists and trees. To solve this without server latency, I built PyViz , a zero-lag, completely in-browser python code visualizer powered by WebAssembly (Pyodide). Why PyViz? Most online execution visualizers rely on backend servers…",
