Graphs They say that a picture tells a thousand words. Pictures remember us little things that will remain in our memories forever. Graphs can also mean as much words as there are in pictures. We can understand and interpret pictures in a graph to learn more from it.
Graphs are drawings that show mathematical information with lines, shapes, and colors. People use graphs to compare numbers or amount of data. Graphs are useful because they can be easier to understand than numbers and words alone.
One of the examples of a graph is a Bar Graph . Bar graph is a chart that uses bars to show comparisons between categories of data. The bars can be either horizontal and vertical
