📈 Line Chart Maker
Paste your data as “label, value” lines and get a clean line chart with a subtle area fill — download it as a crisp PNG or an editable SVG, right in your browser.

Fonts are self-hosted and embedded into the download, so your chart looks identical everywhere. Everything renders in your browser — the data you paste is never uploaded. 🔒
How the line chart maker works
Enter one “label, value” pair per line. The tool plots each value against a gridded axis, connects the points with a smooth 2.5-pixel line, adds a light area fill beneath it and marks each data point. The x-axis labels come from your first column. Everything is drawn as an SVG in the browser, and the PNG export renders it at 2× resolution. Your data is never uploaded.
Line charts are ideal for showing a trend or change over an ordered sequence — months, weeks, versions, measurements. If your categories are unordered and you just want to compare sizes, a bar chart reads better; for shares of a total, use the pie chart maker.
Frequently asked questions
How do I make a line graph online?
Paste your data as “label, value” lines (for example “Jan, 30”), choose a color and optional title, and download. The line chart is generated instantly in your browser — no account, no watermark.
Can I export the line chart as SVG?
Yes — download an editable, infinitely scalable SVG for design tools, or a 2× PNG for slides and documents. Both are generated locally on your device.
Is my data kept private?
Completely. The chart is drawn from the text you paste, entirely in your browser, so nothing is uploaded — it even works offline once the page has loaded.
What is the difference between a line and a bar chart?
A line chart connects values in order to show a trend over time or a sequence; a bar chart compares independent categories by height. Use a line for “how did it change,” a bar for “which is biggest.”
How many data points can I plot?
As many lines as you paste — the axis and spacing rescale automatically. Very dense series still render, though labels read best up to a few dozen points.
