is an option for Graph, GraphPlot, and related functions that specifies whether edges should be taken to be directed.
By default rules are taken to be directed edges:
Specify undirected edges:
Obtain a CycleGraph with directed edges:
Create a directed graph from a symmetric adjacency matrix:
Show edges as arrows in GraphPlot:
Do not show edges as arrows in LayeredGraphPlot:
DirectedEdges is an option to special graph constructors including PathGraph:
CompleteGraph, GridGraph, and ButterflyGraph:
CycleGraph, StarGraph, and WheelGraph:
CompleteKaryTree and KaryTree:
DirectedEdges->True prevents AdjacencyGraph from creating undirected graphs:
DirectedEdges works with RandomGraph and UniformGraphDistribution:
By default, edges are shown as lines in GraphPlot and TreePlot:
Show edges as arrows:
By default, edges are shown as arrows in LayeredGraphPlot:
This shows edges as lines:
