D2 diagram language — declarative diagrams for architecture, system design, network topology, database schemas, and layered infrastructure diagrams. Renders to SVG/PNG via d2 CLI. Supports sketch mode.
Mermaid diagram syntax — sequence diagrams, flowcharts, ER diagrams, Gantt charts, state diagrams, class diagrams, and more. Renders to SVG/PNG via mmdc CLI. Native GitHub/markdown rendering support.
Financial consolidation — multi-entity rollup, intercompany elimination, currency translation, CTA, NCI/minority interest, segment reporting.
Expense and OpEx analysis — run-rate, cost per head, OpEx vs CapEx, vendor concentration, fixed vs variable decomposition, SG&A leverage.
FP&A financial planning — forecasting, scenario modeling, budgetary control.
Variance analysis — actual vs budget, YoY/MoM/QoQ deltas, bridge decomposition.

Use Excalidraw for:
Excalidraw is the "casual" renderer. Use it when the user wants something that looks hand-drawn, not polished.
