## What it is
Crabviz is an LSP-based tool that generates interactive call graphs for many programming languages. It is distributed as a VS Code extension and can export graphs as HTML or SVG.

## Use cases
- visualize call hierarchy of a function
- generate an overview call graph for selected files
- explore unfamiliar codebase structure interactively
- export call graphs as HTML or SVG for sharing
- navigate to definitions directly from a graph
- see file-level relationships in a project

## When to avoid
- you need a standalone CLI tool outside an editor
- your language has no LSP server available
- you need runtime/dynamic call graphs rather than static analysis

## Facets
- artifact type: plugin
- maturity: active
- function: static-site-generator, developer-tools, parser
- domain: developer-tools, documentation, programming-languages
- platform: editor-plugin, cross-platform
- tags: call-graph, lsp, static-analysis, vscode-extension, code-visualization
