Enhanced Interaction and Navigation in JSON Schema Studio

JSON Schema Studio visualizes JSON Schemas as interactive graphs, helping developers understand complex structures. While the current version works well, there are areas where rendering correctness and user experience can be improved. This project focuses on ensuring correct dependency-based rendering (especially for $defs), improving graph navigation, and enhancing synchronization between the editor and visualization. It will also address issues like edge collisions and unstable rendering during live edits. Additionally, features like validation error navigation, file upload, and visualization export will be introduced to improve usability. The final deliverables include: - Dependency-aware rendering using topological sorting - Improved graph interaction and navigation - Validation error navigation in the editor - Reduced edge collisions - Stable rendering during live edits - File upload and export support These improvements will make the tool more accurate, interactive, and useful for developers.
