Pranay-Dommati/code-visualizer ? reverse-engineered prompt

Build me a simple code visualizer app with a frontend and a backend.

I want to paste in code and see it turned into something easier to understand, like a visual breakdown of the structure, maybe highlighting functions, files, and how parts connect. It should feel clean and easy to use, with a text box to enter code, a button to generate the visualization, and a nice area to display the result.

Please make it work as a full app, not just a mockup, and wire the frontend to the backend so the input gets processed properly. If there are any choices to make about the best way to display the code structure, use your judgment and make it look polished. Keep it simple, modern, and responsive so it works well on different screen sizes.

If you need to look up current docs or best practices online while building it, go ahead.
