Complete D3.js property panel integration
Features added: - Full property panel integration with D3 renderer - Node editing: text, shape, colors with live visual updates - Edge editing: labels, types, colors, widths with live updates - Element selection with visual highlighting - Delete functionality for nodes and edges with cascade cleanup - Bidirectional sync: D3 visual changes → Mermaid code updates - Shape transformation support (rectangle ↔ circle ↔ diamond) - Real-time code generation preserving all styling D3 renderer now has feature parity with Mermaid renderer plus: ✅ Persistent positioning (no jumping back!) ✅ Smooth drag & drop interactions ✅ Live property editing with instant visual feedback ✅ Complete bidirectional synchronization 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
