Graphic
From Graal Bible
Graphics are things that talented people make for games, sites, almost anything to do with technology. Graal uses Raster graphics such as JPEG, GIF, and PNG formats. The GIF and JPEG are currently being replaced by PNG as per Stefan's request. Vector graphics are not implemented in Graal's engine and no plans are known if they will be implemented, however the command showpoly(index,array) will sufficiently accomplish most uses of vector graphics.
