Chart

[1] A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.

They are used in a wide variety of fields, and can be created by hand (often on graph paper) or by computer using a charting application.

[2] On the other hand, data that represents numbers that change over a period of time (such as "annual revenue from 1990 to 2000") might be best shown as a line chart.

Typically the data in a chart is represented graphically since humans can infer meaning from pictures more quickly than from text.

The data may appear as dots or shapes, connected or unconnected, and in any combination of colors and patterns.

In addition, inferences or points of interest can be overlaid directly on the graph to further aid information extraction.
