<div><div>Renders the Groebner fan of an ideal. The output is put into an xfig file if a filename is provided. If no filename is provided then macaulay uses fig2dev to make a png which is displayed by the operating system (see <a href="../../Macaulay2Doc/html/_show.html" title="display various TeX, hypertext, or a URL, in an external application">show</a>).</div>
