:directed is not supported because it applies to the whole graph and not a subgraph. The default is boolean_true, i.e., clustered.Ī relation with an identifier followed by a graph definition ( :node, :edge, :attribute, :node_attribute, :edge_attribute). The default value is boolean_true, i.e., directed.Ī boolean ( boolean_true or boolean_false) indicating whether the subgraphs in the graph should have their ID prepended with cluster_ so that the subgraphs are each rendered in a bounding box. These attributes serve as the default for all edges in the graph.Ī boolean ( boolean_true or boolean_false) indicating whether the graph is directed or undirected. These attributes serve as the default for all nodes in the graph.Ī binary relation of edge attributes as ( attribute, value). These attributes serve as the default for the graph/subgraphs.Ī binary relation of node attributes as ( attribute, value). from and to need to match an identifier in the :node relation.Ī ternary relation of node attributes as ( node_id, attribute, value), where node_id matches an identifier in the :node relation.Īn arity-4 relation of edge attributes as ( from, to, attribute, value), where ( from, to) matches an identifier pair in the :edge relation.Ī binary relation of graph attributes as ( attribute, value). KeyĪ unary relation of node_id identifiers (usually strings or integers) that represent the node IDs.Ī binary relation of edges, represented as ( from, to) pairs of node IDs. 
This section gives an overview of the parameters that can be added to the graph module,įollowed by a set of examples for drawing different graphs.
save(skip_existing=False) if you want to re-write the loaded source.Graphviz (opens in a new tab) provides a variety of parameters used to configure the graph visualization. (specifically the same path that it was loaded from).Ĭall. To skip writing the read source back into the same file You can use _file() (alternative constructor): To directly display the rendered visualization of an existing DOT source file replace ( ' \\ ', '/' ) 'doctest-output/the-holy-hand-grenade.gv.png' write_text ( src, encoding = 'ascii' ) 66 > graphviz. Path ( 'doctest-output/the-holy-hand-grenade.gv' ) > filepath. doctest_mark_exe () > import pathlib > import graphviz > src = 'digraph "the holy hand grenade" ' > filepath = pathlib.
