o arrow-end (string) arrowhead on the end of the path. The format for string is `[-[-]]`. Possible types: `classic`, `block`, `open`, `oval`, `diamond`, `none`, width: `wide`, `narrow`, `medium`, length: `long`, `short`, `midium`. o clip-rect (string) comma or space separated values: x, y, width and height o cursor (string) CSS type of the cursor o cx (number) the x-axis coordinate of the center of the circle, or ellipse o cy (number) the y-axis coordinate of the center of the circle, or ellipse o fill (string) colour, gradient or image o fill-opacity (number) o font (string) o font-family (string) o font-size (number) font size in pixels o font-weight (string) o height (number) o href (string) URL, if specified element behaves as hyperlink o opacity (number) o path (string) SVG path string format o r (number) radius of the circle, ellipse or rounded corner on the rect o rx (number) horisontal radius of the ellipse o ry (number) vertical radius of the ellipse o src (string) image URL, only works for @Element.image element o stroke (string) stroke colour o stroke-dasharray (string) [“”, “`-`”, “`.`”, “`-.`”, “`-..`”, “`. `”, “`- `”, “`--`”, “`- .`”, “`--.`”, “`--..`”] o stroke-linecap (string) [“`butt`”, “`square`”, “`round`”] o stroke-linejoin (string) [“`bevel`”, “`round`”, “`miter`”] o stroke-miterlimit (number) o stroke-opacity (number) o stroke-width (number) stroke width in pixels, default is '1' o target (string) used with href o text (string) contents of the text element. Use `\n` for multiline text o text-anchor (string) [“`start`”, “`middle`”, “`end`”], default is “`middle`” o title (string) will create tooltip with a given text o transform (string) see @Element.transform o width (number) o x (number) o y (number) > Gradients * Linear gradient format: “`‹angle›-‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`90-#fff-#000`” – 90° * gradient from white to black or “`0-#fff-#f00:20-#000`” – 0° gradient from white via red (at 20%) to black. * * radial gradient: “`r[(‹fx›, ‹fy›)]‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`r#fff-#000`” – * gradient from white to black or “`r(0.25, 0.75)#fff-#000`” – gradient from white to black with focus point * at 0.25, 0.75. Focus point coordinates are in 0..1 range. Radial gradients can only be applied to circles and ellipses. > Path String #

> Colour Parsing #
    #
  • Colour name (“red”, “green”, “cornflowerblue”, etc)
    • #
  • #••• — shortened HTML colour: (“#000”, “#fc0”, etc)
    • #
  • #•••••• — full length HTML colour: (“#000000”, “#bd2300”)
    • #
  • rgb(•••, •••, •••) — red, green and blue channels’ values: (“rgb(200, 100, 0)”)
    • #
  • rgb(•••%, •••%, •••%) — same as above, but in %: (“rgb(100%, 175%, 0%)”)
    • #
  • rgba(•••, •••, •••, •••) — red, green and blue channels’ values: (“rgba(200, 100, 0, .5)”)
    • #
  • rgba(•••%, •••%, •••%, •••%) — same as above, but in %: (“rgba(100%, 175%, 0%, 50%)”)
    • #
  • hsb(•••, •••, •••) — hue, saturation and brightness values: (“hsb(0.5, 0.25, 1)”)
    • #
  • hsb(•••%, •••%, •••%) — same as above, but in %
    • #
  • hsba(•••, •••, •••, •••) — same as above, but with opacity
    • #
  • hsl(•••, •••, •••) — almost the same as hsb, see Wikipedia page
    • #
  • hsl(•••%, •••%, •••%) — same as above, but in %
    • #
  • hsla(•••, •••, •••, •••) — same as above, but with opacity
    • #
  • Optionally for hsb and hsl you could specify hue as a degree: “hsl(240deg, 1, .5)” or, if you want to go fancy, “hsl(240°, 1, .5)”
