<summary>Simple Chat App</summary>
<p>This is an interactive polling app that allows users to vote on a specific question. Users can vote for their preferred options and view the results in real-time. The app tracks the votes for each option and stores them in the local storage so the votes persist even after the page is refreshed.</p>
