How to use Chart Generator

  1. Paste CSV or tab-separated data with column names in the first row.
  2. Choose a chart type and the columns to plot.
  3. Review axes, values and units, then download the chart and its source data.

What to check

  • Make sure the selected chart type matches the question and data types.
  • Label axes and units clearly and avoid truncated scales that exaggerate differences.
  • Check every value against the source data before publication.

Supported chart types

Create bar, line, scatter, area, pie and histogram charts from up to 1,000 rows. The tool detects numeric columns and refuses invalid Y values rather than silently treating them as zero.

Reproducible exports

Download SVG for scalable artwork, PNG for a flat image, CSV for the displayed source data and Vega-Lite JSON for an editable chart specification. Processing stays in the browser.

Frequently asked questions

Which data formats are supported?

Paste comma-separated or tab-separated data. The first row must contain unique column names.

Does the chart generator change my data?

No. Numeric values are parsed for plotting; invalid or missing numeric values are rejected rather than filled in.

Can I use the chart in a paper?

SVG is suitable for scalable artwork, but you must verify values, units, captions and the journal’s figure requirements.
