Graphs and Charts is the most efficient method for displaying information in a simple manner. Using this form of representation helps it's viewers to understand and interpret the information more easily and efficiently, which otherwise could be a very difficult and tedious process.

Why use graphs to present data?
Because they...
* are quick and direct
* highlight the most important facts
* facilitate understanding of the data
* can be easily remembered
There are many different types of graphs that can be used to convey information, including:
* bar graphs
* pictographs
* circle graphs/pie charts
* line graphs
* scatterplots
* histograms
* A bar graph may be either horizontal or vertical. The important point to note about bar graphs is their bar length or height—the greater their length or height, the greater their value.
* Bar graphs are one of the many techniques used to present data in a visual form so that the reader may readily recognize patterns or trends.
A pictograph uses picture symbols to convey the meaning of statistical information. Pictographs should be used carefully because the graphs may, either accidentally or deliberately, misrepresent the data. This is why a graph should be visually accurate.

A circle graph/pie chart is a way of summarizing a set of categorical data or displaying the different values of a given variable (e.g., percentage distribution). This type of chart is a circle divided into a series of segments. Each segment represents a particular category. The area of each segment is the same proportion of a circle as the category is of the total data set.
Line graphs, especially...
