Bug Report

ImportError: cannot import name 'Table' from 'perspective' - in table_tutorial.ipynb

Steps to Reproduce:

Downloaded notebook.
Created new Python venv.
Installed dependencies (key one is perspective-python).
Executed notebook (within VS Code).
Failed with error below at the initial import step. (I also tried a few typical Python tweaks to get the import to work without success).

Also tried the same experiment in Google Colab with the same error (after pip install of perspective-python).

Expected Result:

As per tutorial documentation.

Actual Result:

ImportError Traceback (most recent call last)
Cell In[2], line 1
----> 1 from perspective import Table
2 from datetime import date, datetime
3 import numpy as np

ImportError: cannot import name 'Table' from 'perspective' (/Users/username/code/github/databooth/tech_blog/.venv/lib/python3.11/site-packages/perspective/init.py

Environment:

Local environment (clean venv created just for testing out Perspective in a Jupyter context)

macOS 14.6.1 (23G93)
VS Code Version: 1.93.1
perspective-python==3.1.0
Python 3.11.10
notebook==7.2.2
pywidgets==8.1.5

Also tried independently on Google Colab (with a pip install of perspective-python) and received the same error.

Additional Context:

Nice work on the package - examples look cool and useful.

Please note that I also noticed some broken links in the Python API docs from this page:
https://perspective.finos.org/docs/python/

We do not offer a top level Table class constructor anymore, to make a table, create a Client and call client.table(...). Here is an example of usage

Please refer to the up-to-date docs on docs.rs. I've created #2777 to track 3.x documentation updates, closing this issue.
