Line & Area Graph Maker
Paste your data below, pick a shape and a theme, and watch the chart update live. Paste multiple value columns for multiple lines — everything runs in your browser, nothing is uploaded anywhere.
Share links carry the data inside the link itself — nothing is uploaded.
Is this free and private?
Yes. This maker builds line and area graphs entirely in your browser — nothing you type is ever uploaded anywhere. There's no signup and no usage limit. The only thing this site measures is anonymous page views, through Cloudflare Web Analytics, which sets no cookies and never sees your data.
How do I embed the chart on my own page?
Click "Copy embed" to copy a script tag plus a <live-chart> element carrying
your current spec as JSON. Paste it into any HTML page and the chart renders live — no build
step required. (The embed loads one hosted file from meikucharts.com; an npm package is planned
but not yet published.)
Can I export the chart as an image?
Yes. "Download PNG" renders the current chart onto an offscreen canvas at 2x resolution and downloads it — useful for slides, docs, or anywhere embedding live HTML isn't practical.
