Data Visualization

Build accessible, performant data visualizations using modern libraries. Choose the right chart type, implement responsive layouts, and optimize for large datasets.

Chart Type Selection

Choose charts based on data relationships, not aesthetics.

BAD - Wrong chart for the task:

// Pie chart for comparing 12 categories - hard to compare angles
<PieChart width={400} height={400}>
  <Pie data={monthlyData} dataKey="value" nameKey="month" />
</PieChart>
