chartjs Uncaught ReferenceError: Utils is not defined
/* The chartjs team decided to use an random/obscure utils file in
all of there code samples.You will need to download the utils file
and maybe rework it to get the samples working, but the chartjs team
basically says don't use their utils bc it will break, so you may be
better of just looking at what it does and pulling in the needed
functions or replacing any Utils references with your code*/
