CGM provides a means of graphics data interchange for computer representation of 2D graphical information independent from any particular application, system, platform, or device~~. CGM was developed by W3C in 1999~~. As a [[metafile]], i.e., a file containing information that describes or specifies another file, the CGM format has numerous elements to provide functions and to represent entities, so that a wide range of graphical information and geometric primitives can be accommodated. Rather than establish an explicit [[graphics file format]], CGM contains the instructions and data for reconstructing graphical components to render an image using an object-oriented approach.
