jayjiratta/Air-Pollution-Forecast-Dashboard — reverse-engineered prompt

Build me a simple air pollution forecast dashboard for Trang that predicts and visualizes PM2.5 and PM10 levels using historical air quality data.

I want the app to let users choose a date range between January 1, 2024 and March 9, 2024, then show clear charts for the predicted pollution levels and related environmental factors. It should feel like an easy web dashboard, not a notebook, with clean styling and labels normal people can understand.

Include the full workflow, data preprocessing, model training, saving the trained models, and running the dashboard locally. Use the existing CSV data if available, and train the PM2.5 model with an Extra Trees style regression approach. If model files are missing, the project should explain that the notebooks or training step need to be run first.

Please make it easy to install, run, and troubleshoot. Look up current docs online if you need to.
