graphics (Sometimes called "object-oriented" graphics,

though it's nothing to do with object-oriented programming).

The representation of separate shapes such as lines, polygons

and text, and groups of such objects, as opposed to bitmaps.

The advantage of vector graphics ("drawing") programs over

bitmap ("paint") editors is that multiple overlapping elements

can be manipulated independently without using differenet

layers for each one. It is also easier to render an object at

different sizes and to transform it in other ways without

worrying about image resolution and pixels.
