Gradients consist of continuously smooth color transitions along a vector
from one color to another, possibly followed by additional transitions along
the same vector to other colors. SVG provides for two types of gradients:
linear gradients and radial gradients.

        :param offset: is either a <number> (usually ranging from 0 to 1) or
          a `<percentage>` (usually ranging from 0% to 100%) which indicates where
          the gradient stop is placed. Represents a location along the gradient
          vector. For radial gradients, it represents a percentage distance from
          (fx,fy) to the edge of the outermost/largest circle.
        :param color: indicates what color to use at that gradient stop
        :param opacity: defines the opacity of a given gradient stop
