About Chart Maker Hub

Chart Maker Hub is a collection of free chart and graph makers that run entirely in your web browser. We built it for students, teachers, analysts, marketers and anyone who needs a clear chart quickly, without installing software, creating an account or uploading data.

What we care about

• Accuracy. Charts should represent data honestly. Bars start at zero, bubble and polar-area sizes scale by area, statistics such as quartiles and regressions use documented methods, and invalid values are reported, never silently changed.
• Privacy. Your data never leaves your device. There are no user accounts and no server-side processing.
• Accessibility. Keyboard-friendly editors, screen-reader descriptions and data tables for every chart, colorblind-safe palettes and pattern fills.
• Free access. Every feature is free. The site is funded by advertising, which never covers the editor.

How it works

Charts are rendered as vector graphics by a rendering engine built on the open-source D3 modules. PDFs are generated in the browser with jsPDF and svg2pdf.js. The same engine produces the live preview and every download, so what you see is what you get.
