It seems that the browser is choking on having all the datapoints in one line, causing it to throw the error "Uncaught SyntaxError: missing ) after argument list
".
I have tried with fewer points and it works well.
I would think that this can be fixed by generating a newline in the code between each datapoint.
Best regards,
