Improving the Triage Workflow Diagram Accessibility

Your suggestions for improving the accessibility of the triage workflow diagram are excellent and align well with Django's commitment to accessibility. Based on the information from Django's documentation about reporting UI issues and accessibility support, here are my thoughts on your proposed changes:

Image of Text

Converting parts of the diagram into text content is an excellent suggestion. This would make the information:

• Resizable for users who need larger text
• Accessible to screen readers
• Searchable within the page
• Easier to maintain and update

The workflow steps could be presented as a structured text description alongside a simplified diagram that shows the relationships visually.

Alt Text

You're absolutely right that the current alt text is insufficient. A comprehensive text alternative should describe:

• The workflow stages
• The relationships between stages
• The roles involved (Triagers vs. Mergers)
• The decision points in the process

This could be implemented either as:

1. A detailed alt text attribute
2. An ARIA-described-by relationship to a full text description elsewhere on the page

Color Perception

Your suggestions for addressing color perception issues are spot-on:

1. Adding stroke-dasharray="4" to the Mergers arrows provides a visual distinction beyond just color
2. Changing the "completed" green to a shade with different luminance improves visibility for users with color vision deficiencies

The grayscale preview demonstrates how these changes would benefit users with various forms of color blindness.

Additional Recommendations

1. Structured Data: Consider providing the workflow as a structured data format (like JSON) that could be consumed by assistive technologies or alternative visualizations.

2. Interactive Version: For the web version, an interactive SVG with proper ARIA attributes could allow users to navigate the workflow using keyboard or screen readers.

3. Simplified Version: Create a simplified version that focuses only on the essential flow, reducing cognitive load.

4. Screenshots: When submitting the final changes, include before/after screenshots to demonstrate the improvements, as mentioned in the "Reporting user interface bugs and features" section of the documentation.

These changes would significantly improve the diagram's accessibility while maintaining its usefulness for all users, aligning with Django's goal of supporting a wide range of assistive technologies.
