amCharts vs Graphs

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.

Graphs is a free Linux desktop application for plotting and manipulating data, released under the GNU General Public License v3.0 or later. It imports column files such as CSV, DAT, XY, and plain text, plus ODS and XLSX spreadsheets, SQLite databases, Panalytical XRDML, Leybold XRY, and Graphs project files. Equations can generate datasets and remain rendered across the plot canvas. Data operations include translation, multiplication, normalization, centering, smoothing, differentiation, integration, Fourier transformation, combining, shifting, cutting, and custom coordinate transformations. Curve fitting offers linear, quadratic, exponential, power-law, logarithmic, sigmoid logistic, Gaussian, and custom-equation models. Results may include parameter confidence margins, confidence bands, R², RMSE, and residual plots. Users can select or create plot styles controlling colors, fonts, lines, markers, error bars, axes, ticks, and grids. Figures export to PNG, JPEG, WebP, SVG, PDF, PostScript, or Encapsulated PostScript, with underlying data export too. Vector output can be edited in applications such as Inkscape. Flathub describes the app as requesting no permissions.
