RAWGraphs

RAWGraphs is a free, open-source data visualization web application for creating advanced, custom chart types from spreadsheets without writing code.

Overview

RAWGraphs fills the gap between spreadsheet charts and code-driven visualization libraries. It runs entirely in the browser, accepts pasted or uploaded data, and offers advanced chart types — circle packing, beeswarm plots, dendrograms, alluvial diagrams, sunbursts — that are hard to build elsewhere without programming. Exports to vector formats drop straight into Illustrator or presentation tools.

As an open-source project, RAWGraphs is free, privacy-friendly (data stays in the browser) and extensible with custom visualization models. It has long been a favorite of data journalists and designers for exploratory, unconventional visuals.

RAWGraphs is developed as an open-source project by densitydesign and Politecnico di Milano, and its library of chart types draws on academic visualization research. Each visualization is configurable — size, color mapping, sorting, grouping — and exports at publication quality. Because processing happens entirely in the browser, sensitive data never leaves the machine, which makes it suitable for confidential analysis. Developers can also embed and extend RAWGraphs through its open codebase.

FAQ

Is RAWGraphs free to use?

Yes, entirely free and open source, with no usage limits.

Does RAWGraphs offer an API?

RAWGraphs is a client-side application; developers can use and extend its open-source codebase programmatically.

How does RAWGraphs compare to alternatives?

It offers advanced visualization types without code, where BI tools lack them and libraries require programming.

Can I use RAWGraphs for commercial work?

Yes — RAWGraphs is open source and free for both personal and commercial use.

What are the main use cases of RAWGraphs?

Designers and journalists use RAWGraphs to create advanced visualizations — beeswarms, alluvial diagrams, circle packings — from spreadsheet data, exporting vector graphics for editorial and design work. Researchers use it for exploratory analysis with unconventional chart types, and privacy-conscious users value that all processing happens locally in the browser.

Does RAWGraphs export high-resolution graphics?

Yes — RAWGraphs exports vector SVG graphics suitable for print and design tools, alongside standard image formats.
