CSV files can probably be read with Python’s csv.DictReader class (from the CSV module) combined with igraph.Graph.DictList(): import csv import igraph reader = csv.DictReader(open(“file.csv”), dialect=“excel”) g = igraph.Graph.DictList(edges=reader) This assumes that the CSV file contains column headers and the columns named “source” and “target” contain the source and target vertex names. If your columns are named differently, use the edge_foreign_keys=… keyword argument of Graph.DictList. — T.
