Compact, responsive chart
The generator maps the smallest and largest values to the drawing area and preserves the order of your series. Equal values produce a flat line. The SVG uses a viewBox so it can scale to the size of its container.
Plain SVG output
Copy or download the generated SVG markup, then paste it into a document or HTML page. It contains a line and point markers without external images, fonts, or scripts.
Local processing
Parsing, preview, and SVG generation happen in this browser. Values are not uploaded or saved.
GOOD TO KNOW
Common questions
What input format is supported?
Enter finite numbers separated by commas, spaces, or line breaks. Up to 250 values are accepted; other text is reported as an input error.
Does it support negative values?
Yes. Negative and positive values are scaled together; the vertical position shows relative size, not a labeled zero axis.
Can I use the SVG in another page?
Yes. Copy the SVG markup or download the file. Its viewBox lets it scale; adjust the width and height attributes for your layout if needed.
