 This package contains everything you need to write figures to standalone HTML files.
 
+> Note: No internet connection or account is required to use plotly.py. Prior to version 4, this library could operate in either an "online" or "offline" mode. The documentation tended to emphasize the online mode, where graphs get published to the Chart Studio web service.  In version 4, all "online" functionality was removed from the `plotly` package and is now available as the separate, optional, `chart-studio` package (See below).  plotly.py version 4 is "offline" only, and does not include any functionality for uploading figures to cloud services.

 ```python
 import plotly.graph_objects as go
 fig = go.Figure(data=go.Bar(y=[2, 3, 1]))
