Graph can be a very useful tool for conveying information especially numbers, percentages, and other data . A graph gives the reader a picture to interpret . That can be a lot more efficient than pages and pages explaining the data .

Graphs can seem frightening, but reading a graph is a lot like reading a story. The graph has a title, a main idea, and supporting details can use your active reading skills to analyze and understand graphs just like any other text .

Bar Graphs

A bar graph has two axes and uses bars to show amounts. In Graph 1 ,we see that the x-axis shows grades that students earned, and the y-axis shows bow many students earned each grade can see that 6 students earned an A because the bar for A stretches up to 6 on thevertical measurement. There is a lot of information we can get from a simple graph like this(See Graph 1).

Line Graphs

A line graph looks similar to a bar graph ,but instead of Bars, it plots points and connects them with a line has  the Same parts as a bar graph – two labeled axes –and can be read the same way read a line graph, it’s important to focus on the points of intersection rather than the line segments between the points, This type of graph is mostcommonly used to show how something changes over is a graph that charts how far a bird flies during the first Five days of its spring migration (See Graph 2).

The unit of measurement for the x-axis is days. The unit of measurement for the y-axis is kilometers. Thus we can see that, on the first day, the pipit flew 20 kilometers. The line segment goes up between Day 1 and Day 2,which means that the bird flew farther on Day 2. If the line segment angled dawn, as between Day 4 and Day 5, it would mean that the bird flew fewer kilometers than the day before. This line graph is a quick, visual way to tell the reader about the bird's migration.

Pie Graphs

A typical pie graph looks like a circular pie. The circle is divided into sections, and each section represents a fraction of the data. The graph is commonly used to show percentages; the whole

pie represents l00 percent, so each piece is a fraction of the whole.A pie graph might include a legend，or it might use icons or

labels within each slice. This pie graph shows on month's expense, (See Graph 3 ).

Food $ 25       Movies $ 12

Clothing $ 36   Savings $ 20    Books $ 7
