Data Visualization Generator
Paste CSV or JSON and turn it into a chart you can download as SVG — all in your browser.
Paste data above (or load the sample) to generate a chart.
How the data visualization generator works
Paste a two-column CSV (label, value) or JSON — an array of {label, value} objects, [label, value] pairs, or plain numbers — and the tool charts it instantly. A header row is auto-detected; the first text column becomes the labels and the first numeric column the values. Switch between bar, line, and pie, then download a crisp, resolution-independent SVG you can drop into a slide, doc, or README. Everything renders locally — your data is never uploaded.
Need to reshape the data first? Convert with the CSV to JSON tool, clean it with CSV Cleaner, or compute stats with the Average Calculator.
Private & free — this tool runs entirely in your browser.
