Quiz
What is the first thing you need to check to decide what is the best geom_ for your plot?
The size of your dataset does not interfere with the type of plot you need to choose, and you can change the colors of your plot at any time.
The number of columns in your dataset does not interfere with the type of plot you need to choose.
The type of the variable you want to plot will define which type of geom will be more appropriate (or even possible to use). For example, if you try to use two continuous variables for a geom_bar plot, the final plot will show many more bars than you need and it will not be informative.
The number of rows in your dataset does not interfere with the type of plot you need to choose.
