Chart Visualization

Chart Visualization

Use this skill to turn structured or semi-structured data into legible visual artifacts for AIFi research. The skill supports static figures, browser-native HTML components, interactive charts, analysis dashboards, diagrams, and Sankey-style flow views.

Workflow

1. Clarify the audience, artifact target, data source, and output format.
2. Read references/chart-selection.md to choose the chart family and data contract. For investment research, also read references/investment-html-gallery.md.
3. Load only the implementation reference needed for the selected environment: investment HTML, static SVG, Python plotting, browser HTML, diagram text, or Sankey flow.
4. Normalize the data before drawing. Keep source labels, units, time ranges, and transformations visible in the artifact or companion notes.
5. Generate the smallest useful artifact first, then iterate on labeling, ordering, annotations, and accessibility.
6. Validate the output with references/quality-gates.md before returning it.
7. Store reusable outputs under the relevant research/targets/<target>/ artifact folder when the chart belongs to investment research.

Method Selection

• Need guaranteed local execution with no packages: use static-svg.md.
• Need a polished investment research artifact that opens directly in a browser: use investment-html-gallery.md and the matching references/html-examples/*.html file.
• Need statistical analysis or print-quality PNG/PDF: use python-analysis.md.
• Need interactive hover, zoom, filters, or browser delivery: use web-interactive.md.
• Need money, users, cohorts, costs, or energy moving between categories: use sankey-flow.md.
• Need architecture, process, causal, or relationship diagrams: use diagram-text.md.

Output

Return:

• artifact path(s)
• chart type and implementation method
• data source and transformation notes
• validation performed
• known limitations or follow-up data needed

Quality Gate

Before finishing, read references/quality-gates.md and confirm that labels, units, source dates, color accessibility, rendering, and artifact paths are all handled.
