This document discusses how graphs can be used to clearly show the relationship between two sets of related facts. It notes that graphs are commonly used in business and technical work, with squared paper often being used to plot the graphs. The graph described in this document plots the percentage of federal personal income tax paid by different income percentiles for the year 2003, using a bar graph to visualize the data.

1. Graph <br />3048001353820When there are two sets of related fact, the relation between them can often be shown clearly by means of diagrams, or graphs. Such graphs are frequently used in all types of business and technical work. Squared paper sometimes called cross sector paper, is generally used for the purpose, and convenient values are assign to the horizontal and vertical division. Two lines at right angels to each other are selected as axis a reference lines, horizontal line is called the X-axis vertical lines the Y-axis. The intersection of these two lines is called origin. <br />This graph is for the Percentage of Federal Personal Income Tax Paid by Different Income Percentiles-2003 and its graph is bar graph <br />
