Ah ha! Thanks Domingo. It appears that the Google Charts documentation
pages also have some use of the autoload parameter with incorrectly
formatted JSON. The solution is that all uses of the autoload parameter
must be changed to use only strict JSON, and if not, you will see a JSON
parsing error.
It is possible you could see JSON parsing errors for other reasons as well,
but the autoload parameter is a big one.
This is new, and we can't easily parse the autoload parameter as non-strict
JSON, so it would be better to make the change now. Alternatively, you can
stop using the autoload parameter entirely, and instead replace it with an
equivalent call of google.charts.load(), maybe including the 'callback'
setting if you need that.
I hope this won't be a huge problem for people to fix. Let us know if
there is a significant reason to delay this change.
