Your assignment is to create one plot to visualize one aspect of this dataset. The plot may be any type we have covered so far in this class (bargraphs, scatterplots, boxplots, histograms, treemaps, heatmaps, streamgraphs, or alluvials)

The plot above is displayed as a bar graph. The bar graph shows how April has the highest amount of flight delays in 2013. What I like about this bar graph is that for the highest amount of delays, April is the month that shows the highest number of flight delays, and it is the brighest so you can easily specify which month has the highest number. of flight delays. What I would like to practice more on is to be able to target specific parts of the data.
