Drawing is a form of visual art in which a person uses
various drawing instruments to mark paper or another two-dimensional medium.
Instruments include graphite pencils, pen and ink, inked brushes, wax color
pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers,
styluses, various metals (such as silverpoint) and electronic drawing.
A drawing instrument releases small amount of material onto
a surface, leaving a visible mark. The most common support for drawing is
paper, although other materials, such as cardboard, plastic, leather, canvas,
and board, may be used. Temporary drawings may be made on a blackboard or
whiteboard or indeed almost anything. The medium has been a popular and
fundamental means of public expression throughout human history. It is one of
the simplest and most efficient means of communicating visual ideas. The wide
availability of drawing instruments makes drawing one of the most common
artistic activities.
