 Convert a Frequency Table Into a Dot Plot
 Frequency table: a table showing the data values and their corresponding frequencies.
 Dot plot: a simplified version of a histogram. Each dot represents a value in that particular category.
 Dot plots are not the same as scatter plots:
 Scatter plots have a set of axes whilst dot plots do not.
 Each dot in a dot plot has a value of 1. As for a scatter plot, we need to refer to the axis for the value of a dot.
