Simple graph and tree plotting

plot_graph(graph, *, vertex_positions[, ...])	Plot the given graph.
plot_partition_tree(tree, *[, altitudes, ...])	Plot the given tree as a dendrogram.
print_partition_tree(tree, *[, altitudes, ...])	Print a partition tree in ASCII format.

plot_graph(graph, *, vertex_positions, vertex_labels=None)

Plot the given graph.

Requires the matplotlib library.

Parameters:

• graph – Input graph

• vertex_positions – 2d array containing the coordinates of each vertex of the graph

• labels – Optional: vertex labels

Returns:

None

plot_partition_tree(tree, *, altitudes=None, n_clusters=0, lastp=30)

Plot the given tree as a dendrogram.

Requires the matplotlib and the scipy libraries.

Parameters:

• tree – Input tree

• altitudes – Tree node altitudes (will default to attribute_regular_altitudes(tree)() if None)

• n_clusters – Colorize the n_clusters largest clusters of the dendrogram with different colors

• lastp – Collapse subtrees containing less than lastp leaves.

Returns:

void
