vector graphics
<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}.
