Summary of Changes

Hello @interstellarmt, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant improvement in the maintainability and customizability of UI components by standardizing their CSS class names. By allowing a configurable prefix, it provides greater flexibility for integration into diverse styling environments and reduces potential class name conflicts. This change affects both axis and legend components, ensuring a consistent approach to styling across these critical charting elements.

Highlights

• Standardized Class Naming: Implemented a consistent class naming convention across axis and legend components to improve maintainability and reduce naming conflicts.
• Configurable Prefix: Introduced a classNamePrefix attribute, allowing users to define a custom prefix (e.g., 'g2-') for all generated class names, enhancing styling flexibility.
• New Utility Functions: Added getAxisClassName, getClassNameFromAttrs, and applyClassName to centralize class name generation and application logic, promoting code reuse and consistency.
• Class Name Mapping: Created CLASSNAME_SUFFIX_MAP to define standard suffixes for various axis sub-components, ensuring uniformity in class naming across the library.

Code Review

This pull request successfully standardizes class names for axis and legend components by introducing a classNamePrefix. The changes are well-structured, with new logic encapsulated in src/ui/axis/utils/classname.ts, which improves consistency and makes components easier to style. I've provided a few suggestions to refactor some of the new logic for improved readability and maintainability. Overall, this is a solid contribution that enhances the library's styling capabilities.
