For example, if edges have both int and float 'weight' attributes, it will be inferred in GraphML that they are both floats (which translates to double in GraphML). ![]() def write_graphml ( G, path, encoding = 'utf-8', prettyprint = True, infer_numeric_types = False ): """Write G in GraphML XML format to path Parameters - G : graph A networkx graph infer_numeric_types : boolean Determine if numeric types should be generalized despite different python values. join () _all_ = from collections import defaultdict import networkx as nx from networkx.utils import open_file, make_str import warnings try : from import Element, ElementTree, tostring, fromstring except ImportError : try : from import Element, ElementTree, tostring, fromstring except ImportError : pass ( 1, mode = 'wb' ) See for the specification and for examples. Instead, it is based on XML and hence ideally suited as a common denominator for all kinds of services generating, archiving, or processing graphs." Format - GraphML is an XML format. Unlike many other file formats for graphs, GraphML does not use a custom syntax. Its main features include support of * directed, undirected, and mixed graphs, * hypergraphs, * hierarchical graphs, * graphical representations, * references to external data, * application-specific attribute data, and * light-weight parsers. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data. "GraphML is a comprehensive and easy-to-use file format for graphs. This implementation does not support mixed graphs (directed and unidirected edges together), hyperedges, nested graphs, or ports. """ ******* GraphML ******* Read and write graphs in GraphML format.
