Pls read below.

Vector graphics is the use of
geometrical primitives such as
points , lines , curves , and shapes or
polygons —all of which are based on
mathematical expressions—to
represent images in computer
graphics . Vector graphics are based
on vectors (also called paths), which
lead through locations called control
points or nodes. Each of these points
has a definite position on the x and y
axes of the work plane and
determines the direction of the path;
further, each path may be assigned a
stroke color, shape, thickness, and
fill. These properties don't increase
the size of vector graphics files in a
substantial manner, as all
information resides in the document's
structure, which describes solely how
the vector should be drawn. [ citation

The term vector graphics is typically
used only for 2D (planar) graphics
objects, in order to distinguish them
from 2D raster graphics , which are
also very common. 3D graphics as
commonly implemented today (e.g.,
in OpenGL) are typically described
using primitives like 3D points and
polygons connecting these (which in
turn describe surfaces); these 3D
primitives are much more similar to
vector graphics than to raster
graphics, but aren't explicitly called
vector graphics . The equivalent of
raster graphics in the 3D world are
voxel-based graphics. [1][2]
Some authors have criticized the
term vector graphics as being
confusing. [3][4] In particular, vector
graphics does not simply refer to
graphics described by Euclidean
vectors . [5] Some authors have
proposed to use object-oriented
graphics instead. [3][6][7] However
this term can also be confusing as it
can be read as any kind of graphics
implemented using object-oriented
programming. [3]

The World Wide Web Consortium
(W3C) standard for vector graphics is
Scalable Vector Graphics (SVG). The
standard is complex and has been
relatively slow to be established at
least in part owing to commercial
interests. Many web browsers now
have some support for rendering SVG
data but full implementations of the
standard are still comparatively rare.
In recent years, SVG has become a
significant format that is completely
independent of the resolution of the
rendering device, typically a printer or
display monitor. SVG files are
essentially printable text that
describes both straight and curved
paths, as well as other attributes.
Wikipedia prefers SVG for images
such as simple maps, line
illustrations, coats of arms, and flags,
which generally are not like
photographs or other continuous-
tone images. Rendering SVG requires
conversion to raster format at a
resolution appropriate for the current
task. SVG is also a format for
animated graphics.
There is also a version of SVG for
mobile phones. In particular, the
specific format for mobile phones is
called SVGT (SVG Tiny version).
These images can count links and
also exploit anti-aliasing. They can
also be displayed as wallpaper.
