Christmas trees sold in the US

So it's Christmas season and I just got this very small data set in my inbox, so I decided, why not go ahead and make some few visualisations using the available data.

First question that comes to my mind is what is the trend of total sales.

My expectation was that it would be steadily increasing, however not much of an increase apart from the boom in 2007, 2013 and 2016.

The second question in my mind would be the trend of sales of fake trees and real trees separately.

As per my expectation, the fake are increasing as the years goes by.

Now finally just to see the trend in percent of fake trees of total in graphical view. From the above graph, I can assume that it should be increasing.

As seen from the above graph, there is some up and down in the trend and not a steady increase.

Happy Christmas and a new year!
