Visualization Builder

Visualization Builder creates data visualizations that communicate insights effectively. It generates code for Python libraries (matplotlib, seaborn, plotly), JavaScript frameworks (D3.js, Chart.js, ECharts), and BI tool configurations (Metabase, Grafana). The skill follows Edward Tufte's principles of data-ink ratio and clear, honest data presentation.

How It Works

1. Data assessment — Analyzes your dataset to recommend the most appropriate chart types
2. Chart selection — Suggests visualizations based on data types and the story you want to tell
3. Code generation — Produces clean, customizable visualization code with proper labels and legends
4. Styling — Applies consistent color palettes, typography, and accessibility-compliant designs
5. Interactivity — Adds tooltips, zoom, filter, and drill-down for web-based visualizations
