I encountered an issue when trying to create the environment using visualization/environment.yml. T
he error indicates that certifi==10000 is an invalid or non-existent version.
This appears to be a typo, and replacing it with a valid version (e.g., certifi==2024.12.14) resolves the issue.

@dellaert This branch was the first UI developed with HTML. This PR was created before we switched to React, so it can now be closed.
