#data-visualization

I need to add charts and graphs to my web application. What are some popular JavaScript libraries for data visualization? Compare libraries like D3.js, Chart.js, and Highcharts based on ease of use, customization options, and performance.

Implement charts quickly with Chart.js. Chart types: 1. Line charts for trends. 2. Bar charts for comparisons. 3. Pie/Doughnut for proportions. 4. Radar for multi-axis data. 5. Scatter for correlations. 6. Mixed chart types. 7. Responsive and accessible. 8. Plugin system for customization. Use react-chartjs-2 wrapper and implement real-time updating with data push.

Craft custom visualizations with D3.js. Patterns: 1. Data binding with selection.data(). 2. Enter/update/exit pattern. 3. Scales (linear, time, ordinal). 4. Axes with d3.axis(). 5. SVG path generation. 6. Transitions for smooth updates. 7. Zoom and pan behaviors. 8. Force-directed graphs. Use Observable Plot for simpler charts or build completely custom. Integrate with React using useRef.
