Chart builder

Values in, honest chart out.

Give the chart a title, enter up to six labeled values, and choose a bar or line. The picture is drawn on this page and can be downloaded as an SVG file. Nothing you type is sent anywhere.

The chart builder needs JavaScript. The steps below, the chart guide and our contact details all work without it.

How to use it

Five steps from numbers to picture.

  1. Title it

    Give the chart a title that says what it shows, in the words your question used.

  2. Enter the values

    Write a label and a number on each row. Leave unused rows empty. Numbers use digits, a minus sign if needed and a full stop for decimals.

  3. Choose the type

    Pick bar for separate categories, or line for values that follow one another over time.

  4. Check the scale

    Leave "Start the value axis at zero" checked unless you have a clear reason to change it, and say so in your caption if you do.

  5. Draw and save

    Press Draw chart. The picture appears below with a table of every value. Press Download SVG once the chart is right.

Before you share it

Ask a stranger to read it first.

Show the chart to someone who did not build it, give them ten seconds, and ask what changed. If their answer is different from yours, go back to the title and the scale before the chart goes anywhere.
