Pie Graph

A pie graph is a circular figure that is broken up into portions that look like slices of pie called sectors. These sectors are used to display relative sizes of data. It is a visually easy way to identify the highest results and lowest results.


Bar Graph

A bar graph is a visual that uses different size bars to provide a visual of different data results. It's purpose is the same as a pie graph, but the results are listed as numerals, not percent of a whole.


Line Graph

A line graph shows information that is connected, like distance over time.
