15.4 Graphic Displays of Data

Here you will display data using bar charts, histograms, pie charts and boxplots.
Two common types of graphic displays are bar charts and histograms. Both bar charts and histograms use vertical or
horizontal bars to represent the number of data points in each category or interval. The main difference graphically
is that in a bar chart there are spaces between the bars and in a histogram there are not spaces between the bars. Why
does this subtle difference exist and what does it imply about graphic displays in general?
