Introduction

The px_classification function in Plotly Express is a powerful tool for creating interactive classification plots. However, with great power comes great complexity, and it can be challenging for users to navigate the various options and parameters available. In this proposal, we outline a comprehensive documentation plan for px_classification to ensure that users can effectively utilize this function to create high-quality visualizations.

Current State of Documentation

While Plotly Express provides a wealth of documentation for its various functions, the documentation for px_classification is limited. The current documentation primarily focuses on the basic usage of the function, without delving into the more advanced options and parameters available. This lack of comprehensive documentation can lead to confusion and frustration for users, particularly those who are new to Plotly Express or classification plots in general.

Parameter Descriptions: Detailed descriptions of each parameter, including their usage, limitations, and default values.
Return Values: A description of the return values of px_classification, including their format and usage.

Implementation Plan

To implement the proposed documentation plan, we will follow these steps:

Conduct a thorough review of the current documentation for px_classification to identify areas for improvement.
Develop a comprehensive outline for the new documentation, including the proposed sections and content.
Create high-quality content for each section, including examples, code snippets, and visualizations.
Review and revise the content to ensure accuracy, clarity, and consistency.
Publish the new documentation on the Plotly Express website, including a clear and concise introduction to the function.

Conclusion

The proposed documentation plan for px_classification aims to provide a comprehensive and user-friendly resource for users to effectively utilize this function to create high-quality visualizations. By following the implementation plan outlined above, we can ensure that the new documentation meets the needs of users and provides a valuable resource for the Plotly Express community.

Future Work

In addition to the proposed documentation plan, we also propose the following future work:

Regularly update the documentation to reflect changes in the px_classification function and Plotly Express.
Conduct user testing to ensure that the documentation meets the needs of users and is easy to use.
Develop additional resources, such as tutorials, videos, and example code, to support users in their use of px_classification.
