New "Grafiek" slide type rendering bar, line and pie charts. Storage fits Marp: a ```chart fenced block holds the spec as JSON. Small charts keep their data inline (the .md stays self-contained); data-driven charts link an external CSV via "source": "data/<name>.csv" kept in a separate data/ directory and packaged into .ocideck like images. On save the inline data is stripped for linked charts (the CSV is the source of truth); on open it is re-hydrated from the CSV. - lib/models/chart.dart: ChartSpec/ChartSeries JSON parse/serialize, inline-vs-source handling, and a CSV parser. - In-app rendering (preview/presenter/PDF/PPTX) via fl_chart. - HTML export renders charts as self-contained inline SVG generated in Dart (no JS chart library); export inlines linked data so the page is standalone. - Editor: type picker, title, a CSV-style data field, and CSV import that can inline the data or link it as data/<name>.csv (with unlink). - Markdown round-trip + .ocideck packaging of linked CSVs; translations for all supported languages. flutter analyze is clean, all tests pass (new chart/CSV/round-trip tests), and the macOS debug build compiles.
