A vector plot is a type of cartesian chart where each point has an X and Y position, a length, and a direction. Vectors are drawn as arrows.

Each vector data point is defined as
[x, y, length, direction].
The length is the relative length of the vector compared to the other vectors. The actual vectors are then rendered so that the
vectorLength option defines the pixel length of the longest vector, and the other vectors are relative to the longest vector.
The direction is given in degrees 0-360, where 0 is north, the arrow pointing downwards.
The rotationOrigin option sets the vector’s point of rotation that could be the center (by default), the tile, or the head.
rotationOrigin also sets the rotation direction (left or right). See the API for full documentation.
