Iterating through an array with a timer - almost there?

Thanks! And yeah learning more about classes is a good idea. However my data still acts weirdly: after a few seconds, the order of the data pulled gets mixed (looping through 2016 and not reaching 2017) and the pace gets really fast as well. I try to replace my table with a proper csv with commas and see if that helps. Did you get the same problem?
