Graphics refer to many spatial shapes that can be divided by contours in two-dimensional space. Graphics are a part of space and have no spatial extensibility. They are limited and recognizable shapes.

Graphics refer to vector drawings composed of external contours, that is, straight lines, circles, rectangles, curves, charts and so on drawn by computers.

Graphics use a set of instructions to describe the content of graphics, and the described objects can be scaled at will without distortion. On the display side, graphics use special software to convert instructions describing graphics into shapes and colors on the screen. It is suitable for describing objects with complex contours and rich colors.
