Side-by-side barcharts

While a contingency table represents the counts numerically, it's often more useful to represent them graphically.

Here you'll construct two side-by-side barcharts of the comics data. This shows that there can often be two or more options for presenting the same data. Passing the argument position = "dodge" to geom_bar() says that you want a side-by-side (i.e. not stacked) barchart.

Load the ggplot2 package.
Create a side-by-side barchart with align on the x-axis and gender as the fill aesthetic.
Create another side-by-side barchart with gender on the x-axis and align as the fill aesthetic. Rotate the axis labels 90 degrees to help readability.
