theboredflamingo/Risk-Assessment ? reverse-engineered prompt

Build me a simple risk assessment app for stocks, focused on Nifty 50 data.

I want a clean web app where I can upload or choose market data, run some preprocessing, and get a risk score or risk level for the selected stock. It should show the main output clearly, along with a few helpful charts or summaries so I can understand why the risk looks high or low. If there are saved model files or prepared data files in the project, use them so the app works right away.

Please make it easy to run locally, and keep the interface simple enough for a non expert to use. If anything is missing, look up current docs online if you need to and fill in the gaps in the most practical way.
