Hey there - I've reviewed your changes - here's some feedback:

  • Move the AI integration into a secure backend service rather than calling OpenAI directly from the client to avoid exposing API keys and improve security.
  • Extract the large inline script and chart setup code into separate JavaScript modules or components to improve maintainability and readability.
  • Refactor repeated chart configuration snippets into reusable utility functions or a factory to reduce duplication and simplify future chart additions.

<issue_to_address>
Tab switching logic does not handle deep linking or browser history.

Currently, tab changes do not update the URL or browser history, preventing direct linking and navigation via back/forward buttons. Please update the logic to modify the URL hash and handle hash changes for better user experience.
