sanjeevans408/statbot-pro ? reverse-engineered prompt

Build me a local app called StatBot Pro that lets a business user drop in a messy CSV or Excel file and ask plain English questions about it, like sales trends by region or how numbers relate to marketing spend.

It should read the data, figure out the answer with pandas, and reply with a clear written summary. If the question calls for a chart, it should make one and save it in a charts folder, then show me a local link or path to open it. I also want basic safe plotting options like bar, line, scatter, hist, and box.

Please make it work in a locked down sandbox so it cannot read random files or run dangerous system commands, and include a simple audit command that proves the sandbox is actually blocking those actions. If the AI is unavailable, give fallback answers for simple stats like mean, median, sum, min, and max. Look up current docs online if you need to.
