    Here is short list of commands available, for more details see SVG path string format or article about path strings at MDN.

  • Catmull-Rom curveto is a not standard SVG command and added to make life easier.
    • -Note: there is a special case when a path consists of only three commands: M10,10R…z. In this case the path connects back to its starting point. -

Coordinates specify a linear gradient vector as -x1, y1, x2, y2, or a radial gradient as cx, cy, -r and optional fx, fy specifying a focal point away -from the center of the circle. Specify <colors> as a list -of dash-separated CSS color values. Each color may be -followed by a custom offset value, separated with a colon -character. -
