Title: Adds default fill & stroke colors if none are provided.

If you define anyone of the 6 graph types without adding a color to the data array:
* fillColor
* strokeColor
* pointColor
* pointStrokeColor
* color

Colors will be created automatically.

These colors are the same for each key in the data array, the opacity is based on the type (stroke/fill/point) and can theoretically scale to any number of colors due to color being derived using a hash of the key.
