"""A collection of :class:`Cartesian3DData` objects.
.. note::
When serializing to JS literals, if possible, the collection is serialized to a primitive
array to boost performance within Python *and* JavaScript. However, this may not always be
possible if data points have non-array-compliant properties configured (e.g. adjusting their
style, names, identifiers, etc.). If serializing to a primitive array is not possible, the
results are serialized as JS literal objects.
