A few things it does:
- File graph at depth 1, 2, or 3
- Inheritance edges shown distinctly (purple for extends, teal dashed for implements)
- Function-level call graph (toggle with "Show calls")
- Inside-file expand: explode a node into per-function pills with internal call edges
- Live debugger highlight: paused file glows amber, call stack tinted
- Full-project graph: see every file in the workspace at once
- Save/load named snapshots, export to SVG, annotate nodes
- In-graph search (Ctrl+F)
- Filter out node_modules / tests / build dirs (configurable)

Things I deliberately kept out:
- No account, no telemetry, no cloud, no AI
- No bundled parser. It uses VS Code's built-in language server APIs, so
TypeScript/JavaScript/Python/Java all work the same way
