Generate sparklines as SVG
A sparkline is a small, word-sized chart that shows a trend without axes or labels, designed to sit inline with text or inside a table cell. This generator turns a list of numbers into a compact SVG sparkline, scaling the values to fit the small height and connecting them with a smooth line. A dot marks the final value so the latest point stands out. Enter a series of readings and it draws the trend at the tiny size you choose.
The line is a single polyline scaled between the smallest and largest values, so the shape of the trend is clear even in a few pixels.
Using sparklines
Sparklines excel where space is tight and the trend matters more than exact numbers, such as dashboards, financial tables and status rows. As vector SVG, a sparkline stays crisp at any size and embeds inline in HTML right alongside text. Because it has no axes or gridlines, it reads instantly as a shape, letting a reader scan many of them down a column and compare trends at a glance.
The output is self-contained and standards-compliant. Everything is generated locally in your browser.

Frequently Asked Questions
What is a sparkline?
A small, word-sized chart that shows a trend without axes or labels, meant to sit inline with text or in a table cell.

Why is the last point marked?

Where are sparklines useful?
In dashboards, financial tables and status rows, where space is limited and the overall trend matters more than exact figures.
