Graphs and Tables
(See pages 197–211)
A circle graph represents one whole amount, such as 100%. Each pie-shaped piece of a circle graph represents a part of the whole.
A bar graph organizes information along a vertical axis that runs up and down one side and a horizontal axis that usually runs along the bottom.
A line graph, like a bar graph, has information on both a vertical axis and a horizontal axis. The changing data is shown on a continuous line rather than on a set of bars.
A table is a list of numbers displayed in columns and rows.
