Please uncomment this block and take a look at this checklist if your PR is making substantial changes todocumentation/impacts files in thedoc directory. Check all that apply to your PR, and leave the rest unchecked to discuss with your reviewer! Not all boxes must be checked for every PR :)

If your PR modifies code of theplotly package, we have a different checklist
below :-).

Documentation PR

• I'veseen thedoc/README.md file
• [ Yes] This change runs in the current version of Plotly on PyPI and targets thedoc-prod branch OR it targets themaster branch
• [ N/A instead used plotly.graph_objects ] If this PR modifies the first example in a page or adds a new one, it is apx example if at all possible
• Every new/modified example has a descriptive title and motivating sentence or paragraph
• [ Yes] Every new/modified example is independently runnable
• [ Yes] Every new/modified example is optimized for short line countand focuses on the Plotly/visualization-related aspects of the example rather than the computation required to produce the data being visualized
• Meaningful/relatable datasets are used for all new examples instead of randomly-generated data where possible
• [Yes ] The random seed is set if using randomly-generated data in new/modified examples
• [ Yes] New/modified remote datasets are loaded fromhttps://plotly.github.io/datasets and added tohttps://github.com/plotly/datasets
• Large computations are avoided in the new/modified examples in favour of loading remote datasets that represent the output of such computations
• [Yes ] Imports areplotly.graph_objects as go /plotly.express as px /plotly.io as pio
• Data frames are always calleddf
• [ Yes]fig = <something> call is high up in each new/modified example (eitherpx.<something> ormake_subplots orgo.Figure)
• [Yes ] Liberal use is made offig.add_* andfig.update_* rather thango.Figure(data=..., layout=...) in every new/modified example
• [ Yes] Specific adders and updaters likefig.add_shape andfig.update_xaxes are used instead of bigfig.update_layout calls in every new/modified example
• [ Yes]fig.show() is at the end of each new/modified example
• [ Yes]plotly.plot() andplotly.iplot() are not used in any new/modified example
• [ Yes] Hex codes for colors are not used in any new/modified example in favour ofthese nice ones

Code PR

• I have read through thecontributing notes and understand the structure of the package. In particular, if my PR modifies code ofplotly.graph_objects, my modifications concern thecodegen files and not generated files.
• I have added tests (if submitting a new feature or correcting a bug) or
  modified existing tests.
• For a new feature, I have added documentation examples in an existing or
  new tutorial notebook (please see the doc checklist as well).
• I have added a CHANGELOG entry if fixing/changing/adding anything substantial.
• For a new feature or a change in behaviour, I have updated the relevant docstrings in the code to describe the feature or behaviour (please see the doc checklist as well).
