In their own words
amCharts
amCharts is a JavaScript library for creating charts, maps, stock charts, and Gantt visualizations. amCharts 5 Charts lists more than 60 chart types, Canvas rendering, and a TypeScript-first API, with integration guides for React, Angular, Vue, Svelte, Next.js, Nuxt, Remix, and vanilla JavaScript. Maps includes bundled GeoJSON maps, projections, heat rules, drill-down, and point clustering without requiring a tile server or API key. Stock Chart provides 34 technical indicators, 22 drawing tools, comparison mode, and automatic data grouping. Gantt supports drag-and-drop task editing, dependency links, progress tracking, and export to PNG, JPG, or PDF. Charts describes screen-reader support, keyboard navigation, ARIA attributes, high-contrast modes, and WCAG AA readiness. The library can be installed through NPM, loaded from CDN URLs, or downloaded as standalone JavaScript files for a server. It supports JSON, CSV, and external data URLs and can power embedded interactive dashboards. amCharts is based in Vilnius, Lithuania; amMap began in 2004, and the first chart followed in 2006. The free version offers full functionality and commercial use but displays a small amCharts backlink. Commercial licenses remove branding and are licensed independently for each product. The listed Basic annual license is $80 a year for one developer seat.
