Show HN: A lightweight code visualizer tool for TypeScript and C# projects

I decided to productify my code visualizer tool that I originally built for myself and have now been using in 2 of my projects. There's a quick demo page available now.

I built the app for 2 reasons:

1) Maintaining the shape of a codebase in your head is exhausting for the brain, yet it's necessary to make decisions in development work, and so we gradually build some sort of picture in our head. I think it's slow and unnecessary.

2) After 10 years of working in software engineering, my understanding is that communication is what makes software development expensive. Maybe I can help.

So my vision with this project is to 1) steer the developer away from the exercise of chasing logic flows by frantically jumping between lines of code, only to remain as a communication bottleneck. 2) have a simplified model of the software available as a backdrop for communicating the development work and possible decisions and effects to non-technical team members. 3) Bonus: create a visual-first development experience for back-end, kind of following suit of a react plugin that I made a few months ago: https://github.com/silverveskilt/react-jump2source (Yes, you should definitely check it out if you're working with React).

I'm posting because if enough people resonate with these ideas, I could turn this project into more of an official endeavour. Thanks for your time!!

Also let me know if you have an alternative graphic tool that you use for visualizing your codebase!
