-        The object <code>cameraPosition</code> contains three parameters:

-        Parameter <code>horizontal</code> is a value in radians and can have any
-        value (but normally in the range of 0 and 2*Pi).
-        Parameter <code>vertical</code> is a value in radians between 0 and 0.5*Pi.
-        Parameter <code>distance</code> is the (normalized) distance from the
-        camera to the center of the graph, in the range of 0.71 to 5.0. A
-        larger distance puts the graph further away, making it smaller.
         All parameters are optional.
