Picturing distributions with graphs

The type of graph depends on the type of variable (categorical, quantitative, or dates).

Bar plots and pie charts

When our data is described in terms of categorical variables, we often use pie charts or bar graphs to represent it. For example, we access the Consumer Complaint Database from the Consumer Financial Protection Bureau, at http://catalog.data.gov/dataset/consumer-complaint-database ...
