## What it is
Code2flow is a command-line tool that generates approximate call graphs for dynamic languages (Python, JavaScript, Ruby, PHP) by parsing source files into ASTs and connecting function definitions to call sites. It outputs DOT flowcharts visualized with Graphviz.

## Use cases
- generate a call graph for a python project
- untangle spaghetti code and see which functions call which
- find orphaned functions that are never called
- onboard new developers by visualizing codebase structure
- extract a subset of the call graph around a target function
- visualize source code as dot flowcharts

## When to choose
- you work in Python, JavaScript, Ruby, or PHP and want a quick approximate call graph
- you need to understand or document the structure of an unfamiliar dynamic-language codebase
- you want a lightweight CLI that outputs Graphviz DOT files

## When to avoid
- you need a perfectly accurate call graph for duck-typed dynamic code
- you work primarily in statically typed languages like Java or C++
- you need IDE-integrated interactive navigation rather than static diagrams
