Data Visualization

Create quantitative visuals that are analytically sound, immediately readable, and polished enough to ship in a report, memo, slide, dashboard, notebook, widget, or HTML artifact. Treat charts as evidence for a takeaway. Redesign charts that are visually attractive but analytically weak, and revise charts that are technically correct but hard to interpret.

Skill Configuration

User Context

Mandatory pre-answer gate: Invoke data-analytics:user-context in preflight mode by loading data-analytics:user-context and running its preflight script before answering, searching connectors, retrieving evidence, creating artifacts, or drafting output. Do not look for a callable MCP tool named data-analytics:user-context. Use the returned data_analytics_preflight envelope as the source of truth for saved context, source-category mapping, semantic-layer registry, onboarding/final-response obligations, and conditional guidance; use saved context and semantic layers as source-selection inputs, not as substitutes for workflow-time reads from connected or provided sources. Do not read or reinterpret raw plugin state files unless preflight fails, declares required content omitted, local shell access is unavailable, or the user explicitly asks for raw state inspection.

Chart Selection

Common surface forms should be named in the chart contract when the final surface is a report, dashboard, slide, notebook, widget, or HTML artifact.
