The context menu, usually obtained by clicking themouse button in the graph view, offers some other possibilities:
DOT algorithm, default for directed graphs. It produces “hierarchical” or layered drawings of directed graphs. The layout algorithm lays edges in the same direction (top to bottom, or left to right), and then attempts to avoid edge crossings and to reduce edge length.
NEATO algorithm, default for undirected graphs. It produces “spring model” layouts. It uses the Kamada-Kawai algorithm, which is equivalent to statistical multi-dimensional scaling.
TWOPI algorithm, for directed and undirected graphs. Radial layout, after Graham Wills 1997.
FDP algorithm, for undirected graphs. It produces “spring model” layouts. It implements the Fruchterman-Reingold heuristic including a multigrid solver that handles larger graphs and clustered undirected graphs.
CIRCO algorithm. It produces a circular layout, after Six and Tollis 1999, Kauffman and Wiese 2002. Suitable for certain diagrams of multiple cyclic structures.
Opens a dialog allowing you to specify a layout command executed by the shell. This command should accept one parameter, the graph file name, and write its layout on stdout in the xdot language. This way, you can give specific options to one of the previous commands, or apply a filter modifying your graph before running it through DOT.
Determine the graph type (directed or not) and apply the default algorithm to it, currently DOT and NEATO respectively.
Allows to export the full graph to a png image.
When checked, the Bird's-eye view is displayed when necessary. Otherwise, it is hidden and its positioning menu is disabled.
Configure where to place the bird's-eye view in the graph view. The possible choices are:
Places the bird's-eye view at the top left corner;
Places the bird's-eye view at the top right corner;
Places the bird's-eye view at the bottom left corner;
Places the bird's-eye view at the bottom right corner;
Automatically choose the best position to hide as little of the graph as possible.
