Updating aesthetic labels

In this exercise, you'll modify some aesthetics to make a bar plot of the number of cylinders for cars with different types of transmission.

You'll also make use of some functions for improving the appearance of the plot.

labs() to set the x- and y-axis labels. It takes strings for each argument.
scale_color_manual() defines properties of the color scale (i.e. axis). The first argument sets the legend title. values is a named vector of colors to use.

1
Set the x-axis label to "Number of Cylinders", and the y-axis label to "Count" using the x and y arguments of labs(), respectively.
2
Implement a custom fill color scale using scale_fill_manual(). Set the first argument to "Transmission", and values to palette.
3
Modify the code to set the position to dodge so that the bars for transmissions are displayed side by side.
