Hi @steam-bell-92 , I've added the Pathfinding Algorithm Visualizer to the Utilities Lab with interactive visualization and node controls. The feature has been tested and is working as expected. Live Demo Video and Screenshots have been attached for your ease. Kindly review the PR. If everything looks good, please consider adding the GSSoC labels as well. Thank you! |

- Ensures accessibility and resolves Playwright E2E test failure. - Caches the activeElement when opening projectModal and returns focus upon closure via Escape key or click.
- Fixes issue where was null when the 50ms timeout fired, preventing focus restoration. - Removed invalid copy-pasted code from that could crash the handler before restoring focus.
…ocus restoration - Removed an inline MODAL FIX script in index.html that was prematurely clearing the modal body on Escape, destroying the focused element and breaking the focus restoration flow in js/main.js. - Removed a duplicate, broken openProject event listener from the bottom of js/main.js that was causing ReferenceErrors. - Updated Playwright test locator to specifically target a button inside #projectsSection so that it isn't confused by dynamically injected 'Recently Viewed' cards.

Description
This PR introduces the Pathfinding Algorithm Visualizer to the Utilities Lab. It allows users to visually understand how Dijkstra's Algorithm and A* Search find the shortest path between a start and target node on a 2D grid. The implementation includes interactive mechanics such as drawing walls and real-time visualization controls.
Key Features & Additions:
