CSV Chart Generator
Generate bar, line, pie, and scatter charts from CSV data
About this tool
The CSV Chart Generator turns comma-separated data into bar, line, pie, and scatter charts — right in the browser. Paste a CSV file with a header row, then pick which column to use for the X axis (labels) and which to use for the Y axis (values). Select multiple Y columns to overlay several series on the same chart.
Bar charts compare values side by side with one bar group per X label. Line charts connect data points to show trends over categories or time. Pie charts display a single series as proportional slices with percentage labels. Scatter charts plot two numeric columns against each other for correlation views.
Example: paste month,revenue,expenses followed by monthly data rows, set X to month and Y to both revenue and expenses, then pick the Bar type to see a grouped comparison. Export the result as PNG or SVG.
FAQ
What CSV format does this tool accept? ›
Comma-separated values with a header row. Fields can be quoted with double quotes; commas inside quotes are treated as literal characters. Tabs, semicolons, and pipes are not auto-detected — use the Data Table Viewer for those.
Can I chart more than one Y series at once? ›
Yes. Hold Ctrl or Cmd and click multiple columns in the Y axis selector. Each selected column becomes its own colored series on bar and line charts. Pie charts use only the first selected Y column.
How do I export the chart? ›
Click Export PNG to download a raster image or Export SVG to get a scalable vector file. Both use the current chart as shown on screen at the canvas resolution.
How is this different from the Data Table Viewer? ›
The Data Table Viewer focuses on viewing, filtering, and sorting tabular data. CSV Chart Generator visualizes that data as charts — bar, line, pie, or scatter — with per-column series control.
