How it works

2

Choose your chart type

Select from bar, line, area, pie, doughnut, radar, or scatter. Customize labels and styles.

3

Download or copy

Export your chart as a PNG image, copy the PNG, or save a standalone interactive HTML preview.

Why choose ToolKnit Chart Maker?

Seven useful chart types

Bar, line, area, pie, doughnut, radar, and scatter cover most quick reporting and content needs.

Editable CSV workflow

Paste, normalize, add rows, add series, and inspect how the tool maps your table into chart data.

Presentation-ready styles

Monochrome defaults keep charts clean while still letting you tweak labels, grid, smoothing, and rounded bars.

No data leaves your browser

All chart rendering happens locally via Apache ECharts. Your data is never uploaded or stored anywhere.

Pro Tips

  • ●Use a short first column like Month, Stage, or Metric so labels stay crisp.
  • ●For pie and doughnut charts, pick the series you want to visualize with the dedicated series selector.
  • ●For scatter charts, the first column becomes point names, while two numeric columns map to the X and Y axes.
  • ●If pasted CSV is messy, use Normalize CSV before tweaking chart options.
