A .NET Core library for F# to generate vector graphics in SVG format.

SharpVG is pre-release and the API is still changing. Pull requests and suggestions are greatly appreciated.

Why SharpVG?

  • Allows you to emit SVG using simple F# commands so that you can create graphics and animations that are easy to distribute
  • Ability to render dynamically using Fable to create interactive web pages
  • All basic SVG elements are supported: line, circle, ellipse, rect, text, polygon, polyline, path, image, and groups
  • No understanding of SVG is required and its as easy as using seq, list, or array
  • No external dependencies other than SharpVG are required
  • .NET Core cross platform support on Windows, Linux, and OSX
  • Limited support for SVG animations
  • Limited support for cartesian plotting
  • Reusable styles


let upperLeft = Point.ofInts (10, 10)
let area = Area.ofInts (50, 50)
let style = Style.create (Name Colors.Cyan) (Name Colors.Blue) (Length.ofInt 3) 1.0

Rect.create upperLeft area
  |> Element.ofRect
  |> Element.withStyle style
  |> Element.toString
  |> printf "%A"
<rect stroke="blue" stroke-width="3" fill="cyan" opacity="1" x="10" y="10" height="50" width="50"/>
let center = Point.ofInts (60, 60)
let radius = Length.ofInt 50
let style = Style.create (Name Colors.Violet) (Name Colors.Indigo) (Length.ofInt 3) 1.0

Circle.create center radius
  |> Element.ofCircle
  |> Element.withStyle style
  |> Svg.ofElement
  |> Svg.toHtml "Example"
  |> printf "%s"
<!DOCTYPE html>
<svg><circle stroke="indigo" stroke-width="3" fill="violet" opacity="1" r="50" cx="60" cy="60"/></svg>
