Abstract: A graphics object can be expressed using procedural language embedded in a markup language document. In an embodiment, a drawing space is specified in markup language. A drawing command to arbitrarily draw a graphics object into the drawing space is specified in procedural language. Interpretation of the markup and procedural language commands results in the rendering of the arbitrary graphics object. In another embodiment, there is a browser comprising a rendering engine, an interpreter, and parser. The rendering engine is configured to interpret a markup language instruction that specifies a drawing space as well as drawing commands in procedural language for drawing an arbitrary graphical object into the drawing space. The parser can then parse the drawing commands and convert them into an execution tree of tree objects.
