## Architecture
- **Frontend-only**: HTML/CSS/JavaScript with CDN dependencies (Monaco Editor, Vega-Embed)
- **Storage**: localStorage with Phase 0 schema (id, name, created, modified, spec, draftSpec, comment, tags, datasetRefs, meta)
- **Structure**: Three resizable panels (snippet library, Monaco editor, live preview)
- **No build tools**: Open `index.html` directly in browser
- **Storage**:
- **Snippets**: localStorage with Phase 0 schema (id, name, created, modified, spec, draftSpec, comment, tags, datasetRefs, meta)
- **Datasets**: IndexedDB (unlimited size, multi-format: JSON/CSV/TSV/TopoJSON, inline & URL sources)
- **Structure**: Three resizable panels (snippet library, Monaco editor, live preview) + Dataset Manager modal
- **No build tools**: Open `index.html` directly in browser (needs local server for IndexedDB)
## Current Status
**Completed**: Phases 0-9 (All core functionality including import/export)
**Next**: Phase 10 - Dataset Management
**Completed**: Phases 0-10 (Core functionality + Dataset Management)
**Next**: Phase 11 - Advanced Dataset Features (optional enhancements)
### Key Features Implemented
