igraph is a library collection for creating and manipulating graphs and analyzing networks. It is written in C and also exists as Python and R packages. There exists moreover an implementation for Mathematica. The software is widely used in academic research in network science and related fields. The publication that introduces the software has 1268 citations as of June 5, 2015 (2015-06-05) according to google scholar.
Contents
igraph was developed by Gábor Csárdi and Tamás Nepusz. The source code of igraph packages was written in C. igraph is freely available under GNU General Public License Version 2.
Basic properties
The three most important properties of igraph that shaped its development are as follows:
Characteristics
The software is open source, source code can be downloaded from the project's GitHub page. There are several open source software packages that use igraph functions. As an example, R packages tnet, igraphtosonia and cccd depend on igraph R package. Users can use igraph on many operating systems. The C library and R and Python packages need the respective software, otherwise igraph is portable. igraph is well documented, the C library as well as the R package and the python package
Functions
igraph can be used to generate graphs, compute centrality measures and path length based properties as well as graph components and graph motifs. It also can be used for Degree-preserving randomization. Igraph can read and write Pajek and GraphML files, as well as simple edge lists. The library contains several layout tools as well.
