I think we can safely say that MooTools < 1.6.0 is the cause of the
problem. The old or new methods of loading the Charts API is probably just
one of several factors that can affect the order that the scripts
initialise. If MooTools initialises first, it takes over the Array.from()
method, resulting in the b.split error.
I can confirm that the problem does not occur with MooTools 1.6.
I suppose one could ask if the change in v50 that provoked this problem was
really necessary? Although it's not strictly Google's responsibility to fix
this, if it's an easy change, it would save a lot of people a lot of hassle.
