## Topology

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

## Visualization

VISUAL (%Visual::Polygon::decorations, other options)
Visualizes the complex.
If G_DIM < 4, the GRAPH and the facets are visualized using the GEOMETRIC_REALIZATION.
Otherwise, the spring embedder and the 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.
Possible supplements: MORSE_MATCHING, SUBCOMPLEX, FACES
VISUAL_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the GRAPH.
Returns: Visual::Graph
VISUAL_DUAL_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the DUAL_GRAPH.
Returns: Visual::Graph
VISUAL_MIXED_GRAPH (%Visual::Graph::decorations)
Uses the spring embedder to visualize the MIXED_GRAPH.
VISUAL_FACE_LATTICE (%Visual::Lattice::decorations)
Visualize the HASSE_DIAGRAM of a simplicial complex as a multi-layer graph.
