`stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

##Plot 2: Improve the histogram of Average Temperature by Month

The data plot that I created shows the specific frequencey of every temerature that has been recored and seperated by each month which is color coded. This graph totals up all the same Tempratures that were recorded which gives us the frequency total but then also seperates them by months. This shows how many of the recorded temps are in a specifc month but also how much they contribute to each singular temp. I think the only code that I feel is a bit special in this case is on line #134 to make the temperatures angled which I do feel like is a nice little addition to the flow of the chart
