Allowed attributes:
EdgeColor, EdgeStyle, Hidden, Name, NodeColor, NodeLabels, NodeStyle, Title, VertexColor, VertexLabels, VertexStyle

seed => random seed value for the string embedder

## Visualization

VISUAL_TIGHT_SPAN (options)
This is a variation of VISUAL_BOUNDED_GRAPH for the special case of a tight span. The tropical vertices are embedded according to the METRIC, the others are hanged in between.
Returns: Visual::Graph
VISUAL_BOUNDED_GRAPH (%Visual::Graph::decorations)
Visualize the BOUNDED_GRAPH of a polyhedron.
Possible supplements: DIRECTED_GRAPH, VERTEX_COLORS, EDGE_COLORS, MIN_MAX_FACE
VISUAL_SPLITS
Visualize the splits of a finite metric space (that is, a planar image of a tight span). Calls SplitsTree.
Returns: Visual::FiniteMetricSpace
