[FEATURE]: Education AI Suite - Mind Map tab to display Keyword-Indexed Graph of Class Content

Created by: ashwinvijayakumar

Description Generate a visual mind map from the AI-generated class summary. The mind map should represent key concepts and their relationships, helping educators and ISVs quickly understand the structure and flow of the class content.

Implementation Notes

• The mind map is derived from the text summary generated by the audio pipeline.
• Business unit recommended Qwen2 for summarization and tools like Mermaid or PlantUML to render the tree-structured output
• The mind map should be displayed in the GUI alongside or after the class summary.

Assumptions

• The summary text is already available from the audio pipeline.
• Rendering libraries (e.g., Mermaid.js) can be integrated into the GUI.

Dependencies

• Completion of Issue #1 (Class Summary).
• GUI support for rendering dynamic visual elements.

Expected Output

• A rendered mind map in the GUI showing key topics and subtopics from the class.
• Option to export or save the mind map (optional for MVP).

Acceptance Criteria

• Mind map is generated from summary text.
• Visual is interactive or at least readable in the GUI.
• Tested with at least 3 different class summaries for robustness.
