About Graphmint
Last updated: October 15, 2026
Graphmint is a free chart maker that runs entirely inside your browser tab. You type your numbers or paste them from a spreadsheet, pick a chart type and a palette, and download a PNG or a true vector SVG. It is built and maintained by Damien Yvert, an independent developer.
Why it works the way it does
Most online chart makers ask you to create an account before you can download anything, and a good number put the export behind a paid plan once the chart is finished. That is a poor trade for something as small as drawing a bar chart, and a worse one when the numbers are a salary band, an unpublished result or a client’s revenue.
So Graphmint does none of it. There is no account system, no paid tier, and nothing is held back: every chart type, every palette, PNG, SVG, clipboard and share links are all free, and the small graphmint.app caption on a chart switches off with one toggle. Your data is rendered into a chart by code running on your own machine and is never uploaded, because there is no server to upload it to. Share links work the same way: the whole chart is compressed into the URL itself, so nothing is stored on our side for a link to keep working.
The honest consequence: because the work happens on your device, there is nothing for us to sync. Your charts are autosaved in your own browser, so they survive a reload but do not follow you to another computer, and clearing your site data clears them. That is the price of not holding your numbers, and it is the right way round for this kind of tool.
What it deliberately does not do
Being clear about the edges is more useful than pretending there are none. Graphmint does not import files — data is typed or pasted, not opened from a CSV or XLSX — and it does not do dashboards, live data connections, scheduled refreshes, collaborative editing or comments. It draws six chart families (bar, line, area, pie, donut, scatter) and not maps, Sankey diagrams, Gantt charts, treemaps or statistical plots beyond scatter. There is no API and no CLI.
If what you need is one of those, a spreadsheet, a BI tool or a plotting library will serve you better, and you should use one. Graphmint is for the case where you have a handful of numbers and want a chart that looks considered, in under a minute, without signing up for anything.
Where the defaults come from
The eight palettes are hand-picked rather than generated, which is most of why a Graphmint chart looks settled before you touch anything: each one is a fixed sequence of eight colours, so the second series in a chart is always the same colour as the second series in the chart next to it. You can switch palette and put the chart on a white, cream, dark or fully transparent canvas — but the defaults are chosen so that you do not have to. There is one typeface throughout, deliberately: a chart is not the place to pick a font.
Pie and donut charts compute their own percentages from your numbers rather than trusting typed-in labels to add up to a hundred. SVG export is real vector output, not a PNG in an SVG wrapper, so it stays sharp at any size and can be opened and edited in Illustrator, Figma or Inkscape.

Corrections, bug reports and feature requests are all welcome, and a bug report that names your browser and OS is worth ten that don’t. Write to damienyvert.dev@gmail.com.
