Demo

Generate interactive graph visualizations from your code.

This extension uses language servers to discover relationships between symbols.

Features

1. Draw call graph for file/folder.

Only includes symbols that are defined in the file/folder (including subfolders).
Calls to builtin language features or 3rd party packages are currently ignored.

2. Draw type hierarchy for file/folder:

Only includes symbols that are defined in the file/folder (including subfolders).
Types defined by the language or 3rd party packages are currently ignored.

3. Expand call graph for symbol.

Recursively graph all the callers and callees of a symbol.

4. Expand type hierarchy for symbol.

Recursively graph all the supertypes and subtypes of a symbol.

Actions

cmd+click (ctrl+click on Windows) to Go to Definition.
(coming soon) shift+click to expand a node by depth 1.

Limitations

Currently, only tested against Python codebases using Pylance language server.
Large codebases will often look like spaghetti. Consider graphing deeply nested folders
