Try changing a few things in the path string then click "draw" to see the results. For the other fields, any valid SVG values may be used, so for example the color red could be written as any of: red, #f00, #ff0000, rgb(255,0,0) or rgb(100%,0%,0%). You can also try using some of the examples from the drop down list above if you don't feel ready to start editing the path directly. Remember in the path syntax, upper case letters mean use absolute coordinates and lower case ones mean use relative coordinates.
