## What it is
go-callvis is a development tool that visualizes the call graph of Go programs using pointer analysis and Graphviz dot output. It provides an interactive web-based viewer for exploring call graphs of packages and types.

## Use cases
- visualize call graph of a Go program
- understand unfamiliar Go codebase structure
- explore how packages and functions relate in a large project
- generate dot files of function call relationships
- focus on a specific package's call graph interactively
- group methods by receiver type for code review

## When to choose
- you need to understand or document the structure of a Go codebase
- you want an interactive viewer to navigate call graphs of large projects
- you need static call graph output for analysis or presentations

## When to avoid
- you need runtime or dynamic profiling data rather than static analysis
- your project is not written in Go
- you cannot install Graphviz and need rendered images beyond SVG

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, data-visualization, graphics
- domain: developer-tools, programming-languages, parsers
- platform: go, cli, cross-platform
- tags: callgraph, static-analysis, graphviz, pointer-analysis, code-comprehension
