Hopefully, I'm not being too forward but I updated your python script to be Python 3 compliant.

There were just a few typos in the readme in the CLI examples.

I added an error message for users who pass partition class objects into `fviz_cluster` without a data component. This can occur when a user employs one of the cluster functions...

My initial thoughts are that this package should support the existing diagnostics for structural topic models fit using the stm library. Maybe give the user the option to use that...
