Pictorial representation of numerical data, such as statistical data, or a method of showing the mathematical relationship between two or more variables by drawing a diagram.
There are often two axes, or reference lines, at right angles intersecting at the origin—the zero point, from which values of the variables (for example, distance and time for a moving object) are assigned along the axes. Pairs of simultaneous values (the distance moved after a particular time) are plotted as points in the area between the axes, and the points then joined by a smooth curve to produce a graph.
