A quote about anywidget from the documentation for context:

anywidget is both aspecification and toolset for authoring reusable web-based widgets for interactive computing environments. As a specification, it defines a standard for widget front-end code. As a toolkit, it provides tools for authoring widget front-end code according to the specification, as well as a Python library that simplifies creating and publishing customJupyter Widgets.

This will not affect thego.Figure class. High level explanation of the difference between usinggo.Figure andgo.FigureWidget:

• go.Figure: The chart generated by this object will be interactive on theclient side. For many purposes, this is all a user needs to do with a chart. The interactions are things like zooming in, or any of the various operations in the toolbar.
• go.FigureWidget: The difference here is that the figure is interactive on theserver side as well.
  • Interactions with the plotly chart can be sent to the python kernel and used in other widgets.
  • Interactions with other widgets can be used to control the chart
