How could I draw this directed graph using LaTeX?
I know the following code:
\documentclass[12pt]{article} \usepackage{tikz} \usetikzlibrary{graphs,graphs.standard} \tikzgraphsset{declare={polygon_n}{[clique]\foreach\x in\tikzgraphV{\x/}}} \begin{document} \begin{center} \tikz\graph[clockwise, nodes={circle, node distance=4cm, fill=blue, inner sep=1}] { polygon_n[n=5] }; \end{center} \end{document} Thanks.
If you don't need the rotation you can use subgraph C_n [n=5, counterclockwise], provided by the graphs.standard library to get the basic shape. Then it's just a matter of setting the style of the nodes and edges, as in the example below:
\documentclass[12pt]{article} \usepackage{tikz} \usetikzlibrary{graphs, graphs.standard} \begin{document} \begin{center} \begin{tikzpicture} \graph [ nodes={draw, circle, fill=red!20}, % style of nodes edges={-latex}, % style of lines between nodes radius=2cm % size of graph ] { subgraph C_n [n=5, counterclockwise] }; \end{tikzpicture} \end{center} \end{document}
