format-chart

Render brand-aware data charts (bar, line, waterfall, sankey, sunburst, treemap, funnel, heatmap, gauge, radar and other Plotly types) to PNG/SVG with the client's compiled brand theme, for embedding in PPTX, DOCX, PDF or HTML deliverables. You author the Plotly figure JSON; the server render_chart tool applies palette and fonts and runs a palette check and visual QA. Use for any chart, plot, graph or KPI visual. Not for process flows, org charts or stakeholder maps (use format-diagram), unbranded Mermaid pie/XY in Markdown (use format-mermaid), or a chart native to an Excel workbook (use format-xlsx).
