Vector Graphics

Vector graphics programs generate images by drawing objects such as rectangles and circles. A source file needs only a small amount of data (such as the colour, line thickness, radius and coordinates of the centre of a circle) to represent an object, so vector graphics files tend to be small. Vector graphics are easily and effectively scaled, as demonstrated in program Draw.

A fractal is included in this section because, although the pixels are plotted individually, the entire complex image can be specified by a small vector of parameters.
