====== Graphviz ======

Graphviz is a software for making graphs using a formal language. The advantage of this software is that the user can focus on relationships, the graph is rendered automatically.

<graphviz dot left 150x250>
digraph { 
a -> b[label="0.2",weight="0.2"]; 
a -> c[label="0.4",weight="0.4"]; 
a -> e[label="0.1",weight="0.1"]; 
c -> b[label="0.6",weight="0.6"]; 
c -> e[label="0.6",weight="0.6"]; 
e -> e[label="0.1",weight="0.1"]; 
e -> b[label="0.7",weight="0.7"]; 
}
