karthikeyan-novactech/react-flow-app ? reverse-engineered prompt

Build me a simple React app for drawing and editing node based flows.

I want a clean page where I can add nodes, move them around, connect them with lines, and see the flow update right away. Make it feel polished and easy to use, with a basic toolbar or controls for creating and managing the diagram, plus a good empty state so it’s clear what to do first.

Use the existing Vite React setup in this project, keep the UI modern and responsive, and make sure it runs smoothly in the browser. If you need to check current docs for the best way to wire it up, go ahead and look them up online.
