A line is the basic element of all art. Every artist has at some point drawn a line. You see line art every day and everywhere--advertisements, posters, product packaging, logos and even mass media like television and the Internet. Line art is the foundation of our visual world..
Line art refers to any form of image that has distinct curved and straight lines put against a plain background. Such artwork does not have gradations in darkness/ shade or color/hue, which represent any 2D or 3D objects.
