Presenting+Data

In chapter 2 you are learning about several different graphs that you can use to present data:
 * Frequency Charts
 * Double Bar Graphs
 * Histograms
 * Line Graphs
 * Circle Graphs

As an easy first assignment for the wiki, I'd like you to create a page with some information about one of the graphs above (I will assign you a graph). On your page, you need to include answer the following questions:
 * What is the graph?
 * What does it look like?
 * When do I use it?
 * How do I make it?

On your wiki page you should all of the following:
 * Each question above in bold face print to set off each section of information (see example here).
 * A picture of the graph
 * Links to two other web pages with more information.
 * Optional: A video that explains how to make the graph or how to use it.
