Graph Command Examples
======================

This section provides examples and documentation for using fromager's graph analysis commands to explore dependency graphs produced by builds.

All examples use the sample graph file ``e2e/build-parallel/graph.json`` which contains the dependency graph for building the ``imapautofiler`` package.

Overview of Graph Commands
--------------------------

The ``fromager graph`` command group provides several subcommands for analyzing dependency graphs:

- ``subset``: Extract a focused subgraph containing only dependencies and dependents of a specific package
- ``why``: Understand why a package appears in the dependency graph
- ``to-dot``: Convert graph to DOT format for visualization with Graphviz
- ``explain-duplicates``: Analyze multiple versions of packages in the graph
- ``to-constraints``: Convert graph to constraints file format
- ``migrate-graph``: Convert old graph formats to the current format

These tools help you understand complex dependency relationships, debug unexpected dependencies, create focused subgraphs for analysis, and create visual representations of your build requirements.
