data-visualizer

Interactive charts transform raw data into visual formats using libraries like Recharts, Chart.js, or D3.js. Build line, bar, pie, scatter, area, and heatmap charts with tooltips, filters, and real-time updates to make data patterns immediately clear and actionable.

Create KPI dashboards in React using Recharts or D3.js with real-time data handling via SSE or WebSockets. Add interactive filters, responsive layouts, and export capabilities (PNG, CSV) to display metrics that update as data changes.

Yes. Each library excels at different chart types and complexity levels. Recharts suits simple dashboards, Chart.js handles standard charts efficiently, and D3.js enables highly custom visualizations. Choose based on your interactivity and customization needs.

Data visualizations require accessibility-conscious color schemes, semantic markup, and keyboard navigation to comply with accessibility standards. Optimize rendering performance for large datasets using library-specific techniques like virtualization and efficient re-renders.

Export capabilities vary by library. Recharts and Chart.js have built-in or plugin-based export to PNG. For CSV exports, prepare your underlying data layer separately; most visualization libraries focus on rendering, not data serialization.
