Third-party IF extension

graph-pandas

graph to pandas

df_nodes, df_edges = pn.graph.ext_networkx.graph_to_dataframe(G)

pandas to graph

G = pn.graph.ext_networkx.dataframe_to_graph(
        df_nodes, df_edges, create_using=nx.Graph()
        )

pandas-data

from/to excel

• from .xlsx w/o note

  df_nodes, df_edges = pn.graph.io.read_graph(filename)
  

• from .xlsx w/ note

  df_nodes, df_edges, df_note = pn.graph.io.read_graph(filename, note=True)
  

• to .xlsx w/o note

  pn.graph.io.write_graph(filename, df_nodes, df_edges)
  

• to .xlsx w/ note

  note = {'x': 1, 'y': 2}
  pn.graph.io.write_graph(filename, df_nodes, df_edges, note=note)
  

to/from csv

df_nodes.to_csv(filename)

df_nodes = pd.read_csv(filename, index_col=0)
