Mudassir-byte/AI-Powered-Customer-Sentiment-Analysis — reverse-engineered prompt

Build me a simple web app for customer sentiment analysis that runs in the browser and feels like a college final year project demo. I want a clean page where someone can paste customer comments or upload a CSV file of feedback and then see whether each entry looks positive, negative, or neutral. It should also show an easy summary of the results, like total records, how many fall into each sentiment, and a basic visual chart so the output feels useful at a glance.

Please include sample data support using the CSV files in the project, and make the interface easy enough for a non technical person to use. If possible, let people test one comment manually as well as analyze a full file. Keep the design neat with HTML, CSS, and JavaScript, and make sure the page is responsive and works locally by just opening the main file. If you need to, look up current docs online and wire up whatever simple approach makes this work cleanly.
