The major advantages of tables are their ease of construction, straightforward interpretation, and ability to read actual numbers. Tables are not terribly visually appealing, however, and can be overwhelming to a reader if they are large. When you want to display data in a time series it is important to design a chart so that it is easy to make comparisons over time. It is difficult to detect patterns of change over time in tables. Line charts are suitable when you want display changes that are large and when there are turning points.
Line charts are easy for the eye to follow and clearly display distinct changes over time.
Scatterplots Scatterplots are used to show the relationship between two quantitative variables. A curve in the chart is often included to show an estimated regression. This gives an overall picture of the relationship between all the dots on the graph. This type of reporting structure is common among ratings of movies, restaurants, colleges and the like because of its simplicity and visually appealing qualities. Simply, this type of reporting is the display of a number of stars or other symbol next to a variable or organization based on the organization's performance or score on the particular variable.
