Build me a Python tool that analyzes a codebase by reading its source files, extracting dependencies, and turning them into a graph I can inspect.

I want it to calculate useful code quality and graph based metrics, then flag modules that look risky or defect prone, and suggest refactoring ideas that are aware of those dependencies. It should also generate a simple report that a person can understand, with clear findings and a modernization plan for a legacy system.

Start with the first milestone, make sure it can build and test a dependency graph from Python files in a local folder, and keep the core analysis independent of any external AI APIs. Please make the code easy to grow step by step, with tests for each part as you go. If you need to look up current library docs online while building it, go ahead.
