RAWGraphs is an open-source web tool for creating custom vector-based visualizations built on the d3.js library. Developed by DensityDesign Research Lab, it bridges the gap between spreadsheet applications and vector graphics editors. The tool works with tabular data (spreadsheets, CSV) and copied-pasted text, outputting SVG visualizations editable in graphics software or embeddable in web pages. RAWGraphs processes all data client-side in the browser, ensuring complete privacy as no server-side operations or storage occurs. It's designed for designers and visualization enthusiasts who need to transform raw data into publication-ready graphics.
