class ExamplePage
  include Blueprint::HTML

  private def blueprint
    svg xmlns: "http://www.w3.org/2000/svg", width: 30, height: 10 do
      g fill: :red do
        rect x: 0, y: 0, width: 10, height: 10
        rect x: 20, y: 0, width: 10, height: 10
      end

<svg xmlns="http://www.w3.org/2000/svg" width="30" height="10">
  <g fill="red">
    <rect x="0" y="0" width="10" height="10"></rect>
    <rect x="20" y="0" width="10" height="10"></rect>
  </g>
</svg>

You should note that SVG elements methods are accessible only inside #svg method block, using a SVG element outside SVG block will result in a compilation error.
