Every chart type has its own page with tips, worked examples and the extra maths it needs: percentages for pies, bins for histograms, quartiles for box plots, a line of best fit for scatter plots.
From spreadsheet to slide in four steps
- Pick a chart type from the row of buttons. The sample data shows you the format to use.
- Paste your data over the sample. Copy the cells from Excel, Google Sheets or Numbers, or type rows like “Latte 42”.
- Add a title, and open “Labels & options” for axis labels, stacking, sorting, colours and image size.
- Download a PNG or SVG, copy the image straight to your clipboard, or copy a share link.
Stuck with messy text rather than a clean table, like a paragraph from a report or survey notes? The AI chart generator pulls the numbers out and picks a chart for you.
Which chart should you use?
Use a bar graph. Bar lengths are the easiest visual to compare precisely.
Built to be honest by default
Good charts don’t mislead. That’s why bars always start at zero, bubbles scale by area rather than radius, and pie charts label their percentages. There’s a colour-blind-safe palette (Okabe–Ito) and a greyscale set for printing, and every chart comes with a text description for screen readers. The idea of seeing numbers, not just reading them, is an old one. Otto and Marie Neurath’s Isotype picture charts of the 1920s inspired this site’s look. ahaboo carries the idea further, letting you work through topics such as how US tax brackets split marginal from effective rates by adjusting the numbers yourself.
Questions
Is ChartCraft really free?
Yes. Every chart type, PNG and SVG download and share link is free, with no signup and no watermark.
Is my data private?
Charts are drawn by JavaScript in your browser, so your data isn’t uploaded. It’s saved in your own browser’s storage so it’s still there next visit. The only time data leaves your device is when you click an AI button (Describe with AI, or the AI chart generator).
Can I paste data from Excel or Google Sheets?
Yes. Copy the cells and paste them into the data box. Tab-separated, comma-separated (CSV) and simple “Label 42” lists are all detected.
How do I share a chart?
Click “Copy share link”. The chart’s data and settings are packed into the link itself, so anyone who opens it sees the same chart and can edit their own copy. Nothing is stored on a server.
What size are the downloaded images?
PNG downloads are rendered at twice the chart size (for example 1600 × 900 for the wide 16:9 layout), so they stay sharp on slides and retina screens. SVG downloads are vector and scale to any size.
Which chart should I use?
Compare categories with a bar graph, show parts of a whole with a pie or donut, change over time with a line or area chart, a distribution with a histogram or box plot, a relationship with a scatter plot, and overlap with a Venn diagram. The guide to types of charts goes deeper.
