Free flowchart, diagram and chart makers

Charts & Graphs

Tools that turn numbers into charts. Type or paste your data from a spreadsheet and the chart redraws as you type: a pie or donut chart with percentages and angles, a line graph with one line per column, a gauge with colored zones and a target mark, or a Sankey diagram that shows how amounts flow from one stage to the next.

You can change labels, colors and the legend, then download the chart as a PNG image, an SVG vector file or a PDF. Your data stays in your browser.

Tools in this group

  • Gauge Chart Maker — Set the value, the scale and the colored zones; the gauge redraws as you type and a sentence tells you how to read it.
  • Line Graph Generator — Type or paste your numbers; the line graph draws as you type, with one line per column and the summary numbers underneath.
  • Pie Chart Maker — Type a label and a number for each slice; the pie chart, its percentages and its angles update as you type.
  • Sankey Diagram Generator — Write one flow per line, or paste rows from a spreadsheet. The Sankey diagram draws as you type and you can drag the nodes into order.
