When the data is large, its visual representation can be very useful. You cannot expect every user of the data or report to look closely at every number or number and then extrapolate for himself. That's why we present information through images and charts. Graphics is a very popular visual device for representing data, information and knowledge. Chart can be used to depict raw data or indicate trends. This makes it easier for the human eye to understand an image, rather than a bunch of disorganized numbers. There are many types of graphs, such as line chart, area chart, pie chart, bar chart and so on. Today, I'm going to publish a psd of line diagram and area diagram. Everything about this graphic is customizable--whether it's the color scheme, the value, or the nature of the graphic (line or region). You can represent any variable and its value by making minor changes to the feature psd. Such diagrams are often used in presentations and executive summaries.
