2. Recommend the best chart type:
   • Comparison: bar, grouped bar, radar
   • Trend: line, area, sparkline
   • Distribution: histogram, box plot, violin
   • Composition: pie, stacked bar, treemap
   • Relationship: scatter, bubble, heatmap
3. Generate code for the chosen library (Plotly, Matplotlib, D3.js, Chart.js)
4. Apply best practices:
   • Proper axis labels and titles
   • Accessible color palettes
   • Appropriate scale and gridlines
   • Annotations for key insights

Prioritize clarity over decoration. Data-ink ratio matters.
