Visualize call structures as directional graphs (incoming/outgoing) to better understand your code’s structure.
Language-agnostic — works with any language that supports Call Hierarchy. (see Requirements)
Features
Bidirectional Call Graphs
Visualize call graphs in both directions:
Outgoing Call Graph — Shows functions called by the selected function.
Incoming Call Graph — Shows functions that call the selected function.
Focused View
Cut out the noise and focus on the call structure you care about.
Hide individual files or functions by clicking the × icon.
Right-click a node → "Show Path to Root" to display only the path from that node up to the root.
Jump to Definition
Click any function to jump straight to its definition.
PlantUML Export
Click the "Export PlantUML" button in the top toolbar to export the current graph as PlantUML.
Getting Started
Open a source file in the editor.
Place the cursor on the function you want to visualize.
Use one of the following:
Context menu (right-click):
Show Incoming Call Graph
Show Outgoing Call Graph
Keyboard shortcuts:
Ctrl+Alt+Q — Show Incoming Call Graph
Ctrl+Alt+W — Show Outgoing Call Graph
Command Palette:
Ctrl+Shift+P → Call Graph Navi: ...
Requirements
A language server with Call Hierarchy support must be installed and active for the target language (e.g. ms-vscode.cpptools, clangd, rust-analyzer, Pylance, gopls).
Known Issues
Rendering large graphs may take longer depending on their size.
