v0.2

Mermaid Diagram Support

This release adds full Mermaid diagram rendering as native PowerPoint shapes — no rasterized images, fully editable in PowerPoint.

Supported diagram types

• Flowcharts — all standard node shapes (round, stadium, subroutine, cylinder, circle, diamond, hexagon, trapezoid, double-circle)
• Sequence diagrams — participants, messages, and activation boxes
• Class diagrams — classes with attributes/methods and relationships
• State diagrams — states, transitions, start/end nodes, and cyclic transitions
• Journey diagrams — task timelines with sections and scoring
• ER diagrams — entities, attributes, and relationship connectors

Layout and rendering

• Graph-based layout using topological sorting and longest-path layering for optimal node placement
• Curved connectors with proper arrowheads between shapes
• Back-edge routing around intermediate nodes for cyclic graphs
• Label-arrow collision avoidance with virtual bounding boxes for text
• Connector snapping to correct connection points on shapes
• Edge overlap reduction for cleaner diagrams
