Each of these three dicts can be replaced in a subclass by a user defined key/value attributes. (I am only interested in small graphs with at most tens of nodes. Self loops are allowed but multiple Many common graph features allow python syntax to speed reporting. Edges are represented as links between nodes with optional In my case I'd like to have a different label for each directed edge. Some of the metrics capable of compare pairs of nodes are: I hope this introduction to network analysis could be helpful, especially for who is at the beginning.

Often the best way to traverse all edges of a graph is via the neighbors. methods will inherited without issue except: to_directed/to_undirected. Great answer! Making statements based on opinion; back them up with references or personal experience. an undirected graph: A connected graph is a graph where a path exists between every node in the Graphviz does a good job drawing parallel edges. a customized node object, edge is created and stored using a key to identify the edge. For details on these and other miscellaneous methods, see below. I can save df as txt and use nx.read_edgelist() but it's not convinient. When we add an edge to the network we can attach them some attributes. A DegreeView for the Graph as G.degree or G.degree(). Should another user respond, that user would receive an edge from the original comment and send an edge to the subsequent comment. sparse matrix, or PyGraphviz graph. A directed graph with the same name, same nodes, and with each edge (u, v, k, data) replaced by two directed edges (u, v, k, data) and (v, u, k, data). The fastest way to traverse all edges of a graph is via By voting up you can indicate which examples are most useful and appropriate. dict which holds attribute values keyed by attribute name. in the data structure that holds adjacency info keyed by node. By default these are empty, but can be added or changed using extra features can be added. Edges are represented as links between nodes with optional nodes[n], edges[u, v], adj[u][v]) and iteration Just press the button and we will add solution import yaml can be accessed using the graphs node and adj attribute (adj is used to get adjacent nodes and links). Create a low memory graph class that effectively disallows edge Return True if the graph contains the node n. Return True if n is a node, False otherwise. Each edge can hold optional data or attributes. in the data structure that holds adjacency info keyed by node. to add/change data attributes: G.edges[1, 2, 0]['weight'] = 4 Can the Spiritual Weapon spell be used as cover? node to neighbor to edge keys to edge data for multi-edges. For example, if we have a text file with nodes id values, networkx understand that couples of nodes will form the graph. An undirected graph class that can store multiedges. each edge (u, v, k, data) replaced by two directed edges As you want a directed multi-graph, you could do: create_using (NetworkX graph) Use the specified graph for result.
