Different tool to understand codebases explaining all the features implemented in a codebase visually

[axelreichwein]

Given the interest in the Pocket Flow project to understand codebases, I wanted to inform you about a similar tool that I've built that explains all the features implemented in a codebase visually, by showing its feature hierarchy, and associated code.

As an example, for the open-source codebase of the Spot robot SDK from Boston Dynamics with 100k lines of code, this is the related feature map (no login required, normal screen size required): https://product-map.ai/app/public?url=https://github.com/boston-dynamics/spot-sdk

I've attached an image below to show you a snippet of the interactive zoomable feature map.

I would be curious to hear your thoughts about it. For what kind of codebases would you find this feature map useful? What other kinds of feature-first visualizations would you like to have (e.g. sequence or state machine diagram inspired)?
