A real open-source charting application

This Free4AllHub edition is built from RAWGraphs, designed and developed by DensityDesign, Calibro and INMAGIK with contributors. It preserves the 32 built-in chart types and local data mapping workflow. It is an independently modified edition, not the original hosted app.

Upstream app version 2.1.0, source commit 48c3b2ee9ff412721a2c99c7bed38e734b3fa534. Modifications dated 8 November 2026.

What this edition changes

Removes Google Analytics, external data fetching, URL project loading and arbitrary custom chart code.
Uses system fonts and original synthetic samples rather than remote data.
Does not register or unregister service workers belonging to other apps.
Adds file-size and project checks, guarded vector/picture exports and clearer project-saving guidance.
Uses one shared main-thread chart bundle. Complex data can still be slow; file and table limits are safeguards, not performance guarantees.

A .rawgraphs file includes your data. The app has no cloud save or account. Keep an original copy and check the exported files. The full range of chart/data combinations, touch editing and assistive-technology support are not guaranteed.
