Vector graphics render images using lines and curves, called vectors, that include color and position information. For example, the image of a leaf may be defined by a series of points that describe the outline of the leaf. The color of the leaf is determined by the color of its outline (the stroke) and the color of the area enclosed by the outline (the fill)

This is a picture of the feature being described.

When you edit a vector graphic, you modify the properties of the lines and curves that describe its shape. Vector graphics are resolution-independent, which means you can move, resize, reshape, or change the color of a vector graphic, as well as display it on output devices of varying resolutions, without changing the quality of its appearance.
