Highcharts

Highcharts is a JavaScript charting library and data visualization product suite developed by Highsoft, a company based in Vik i Sogn, Norway. The library has been actively maintained for over 15 years and is used by 80 percent of the Fortune 100 companies, with over 50,000 customers across 140 countries. The product suite includes Highcharts Core for standard charts, Highcharts Stock for financial time-series visualization, Highcharts Maps for geographic data with built-in projections, Highcharts Gantt for project management timelines, Highcharts Dashboards for multi-panel analytics layouts, and the recently launched Highcharts Grid for spreadsheet-style interactive data tables. The library ships with officially maintained framework integrations for React, Angular, Vue, Svelte, JavaScript, TypeScript, Flutter, Python, and Node.js, following each framework's conventions rather than imposing custom patterns. Highcharts features intelligent responsive design that automatically adjusts chart dimensions, label positions, and legend placement based on container size, plus a built-in adaptive theme system that respects user color scheme preferences including dark mode. The accessibility module is one of the most comprehensive in any charting library, generating ARIA descriptions, keyboard navigation, and screen reader support to meet WCAG compliance standards. The newest addition, Highcharts Orbit, adds AI-powered analytics capabilities to any chart including forecasting with fit scores, anomaly detection with visual outlier flagging, natural language data exploration, and automated report generation. Notable customers include Netflix, Samsung, Thomson Reuters, Verizon, Visa, GitHub, Google, Bank of America, BNP Paribas, ICBC, Citi, Johnson and Johnson, Medtronic, CVS, Pfizer, WHO, Salesforce, PayPal, and Crowdstrike. The project has over 12,000 GitHub stars with 3.1 million weekly npm downloads, and offers both free open source and commercial licensing options.
