Free data visualization tools for turning a spreadsheet or a block of text into a downloadable chart, cloud, or graph. Paste rows straight into Data to Chart for an instant bar, line, pie or scatter chart, drop a block of text into Word Cloud Generator to see which words dominate, or plot z=f(x,y) as a rotatable surface with the 3D Surface Plotter.
Every chart renders locally in the browser tab you are already in — no spreadsheet is ever uploaded to a server, and there is no account, watermark, or paywall to unlock a PNG or SVG download. Built for anyone who needs one clean chart for a report, blog post, or presentation without opening Excel or a design suite.
