vegiveera/tableau_langchain_starter_kit ? reverse-engineered prompt

Build me a simple Python app that connects Tableau Server or Tableau Cloud to an AI chatbot so I can ask questions about my Tableau data in plain English.

I want both a small web app and a Tableau dashboard extension version, so I can either test questions in the browser or drop it into a Tableau dashboard. It should let me connect with my Tableau credentials, choose a data source, and then ask things like trends, comparisons, and outliers in the data. Please include a basic command line mode for quick testing, plus a local web page I can open in the browser.

Use environment variables for the API keys and Tableau settings, and make it easy to run locally with clear setup steps. If anything needs current docs or a library update, look it up online and use the latest best practice. Keep it simple, working, and easy for someone to try with the Tableau Superstore example.
