Add a live demo

Hi,
It will be great to have a live demo site so that people can see it in action.
Maybe we can create a GitHub page for it.

Start by reviewing the repository's existing entry points and build or deployment setup; the issue does not name specific files or tests. Clarify what the live demo should show and how it should be hosted, then consider the work done when an accessible GitHub Pages demo is available and demonstrates the project in action.
