Other options:
graph_only => boolean
if true, use the GRAPH for the spring embedder
subcomplex => 'PropertyName'
draw the faces of the given subcomplex in a different color
Allowed attributes:
EdgeColor, EdgeStyle, Hidden, Name, NodeColor, NodeLabels, NodeStyle, VertexColor, VertexLabels, VertexStyle

## Topology

fundamental2gap
Writes the FUNDAMENTAL_GROUP using FUNDAMENTAL_GROUP_GEN_LABELS to the given file in GAP input format.

## Visualization

VISUAL (%Visual::Graph::decorations, [ options ])
Visualizes the complex.
If G_DIM < 4, the GRAPH and the faces of dimension < 3 are visualized using the GEOMETRIC_REALIZATION.
Otherwise, the spring embedder and the MIXED_GRAPH are used to produce coordinates for the visualization.
If JavaView is used to visualize the complex, all faces of one facet build a geometry in the jvx-file, so you may use Method -> Effect -> Explode Group of Geometries in the JavaView menu.
VISUAL_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the GRAPH.
VISUAL_DUAL_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the DUAL_GRAPH.
VISUAL_MIXED_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the MIXED_GRAPH.
