You don't have to use updateData() if you use setCoordinate(), setColor() etc.
updateData() method ensures that the coordinate change and color change happens as
one atomic operation. Using the individual method does not gurantee this.

while the API allows sharing of reference data by several GeometryArray, this is not
recommended and should not be done. We recommend that you share GeometryArray object
and not the reference data themselves.
