What is the best JavaScript charting library for beginners?

Chart.js is the best choice for beginners. With a simple API and excellent documentation, developers typically achieve proficiency within 2 hours. The library handles 90% of common business chart requirements (line, bar, pie) with minimal configuration.

Which JavaScript charting library handles large datasets best?

ECharts handles large datasets best, supporting 10 million+ data points with progressive rendering and automatic performance optimization. The library uses canvas rendering by default, providing smooth interactions even with massive data volumes.

Do I need to pay for JavaScript charting libraries?

No, five of the six major libraries are free and open-source: D3.js, ECharts, Chart.js, Recharts, and ApexCharts. Highcharts requires a commercial license ($250-$500+ annually) for business use.

Can I use D3.js with React?

Yes, but integration is challenging. D3.js manipulates the DOM directly, which conflicts with React's virtual DOM. Developers typically wrap D3 code in useEffect hooks and manage refs carefully to prevent conflicts.

What is the difference between Chart.js and D3.js?

Chart.js is a high-level library providing predefined chart types with simple configuration. D3.js is a low-level library giving complete control over every visual element. Chart.js takes 15-20 lines for a bar chart; D3.js requires 50-100 lines for equivalent functionality.

Which charting library is best for B2B SaaS embedded analytics?

ECharts provides the strongest foundation for customer-facing analytics in B2B SaaS products. However, complete embedded analytics requires infrastructure beyond charting: multi-tenant data architecture, row-level security, dashboard builder, scheduled reports, and embedding SDK.

Should I use Canvas or SVG rendering for charts?

Use Canvas for large datasets and frequent updates (real-time dashboards, 10,000+ points). Use SVG for smaller datasets requiring crisp rendering at any zoom level, print-quality output, or when inspecting elements in browser DevTools.
