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. [2] There exists moreover an interface for Mathematica. [3] The software is widely used in academic research in network science and related fields. The publication that introduces the software has 13502 citations as of July 3, 2024 according to Google Scholar.

Contents

igraph was originally developed by Gábor Csárdi and Tamás Nepusz. [4] It is written in the C programming language in order to achieve good performance and it is freely available under GNU General Public License Version 2.

The three most important properties of igraph that shaped its development are as follows: [4]

Characteristics

The software is open source, source code can be downloaded from the project's GitHub page. [5] There are several open source software packages that use igraph functions. As an example, R packages tnet, [6] igraphtosonia [7] and cccd [8] 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. The C library of igraph is well documented [9] as well as the R package [10] and the Python package [11]

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 file formats such as Pajek, GraphML, LGL, NCOL, DIMACS, and GML, as well as simple edge lists. [12] The library contains several layout tools as well. [4]

The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors. CPAN can denote either the archive network or the Perl program that acts as an interface to the network and as an automated software installer. Most software on CPAN is free and open source software.

Wolfram Mathematica is a software system with built-in libraries for several areas of technical computing that allow machine learning, statistics, symbolic computation, data manipulation, network analysis, time series analysis, NLP, optimization, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages. It was conceived by Stephen Wolfram, and is developed by Wolfram Research of Champaign, Illinois. The Wolfram Language is the programming language used in Mathematica. Mathematica 1.0 was released on June 23, 1988 in Champaign, Illinois and Santa Clara, California.

DOT is a graph description language, developed as a part of the Graphviz project. DOT graphs are typically stored as files with the .gv or .dot filename extension — .gv is preferred, to avoid confusion with the .dot extension used by versions of Microsoft Word before 2007. dot is also the name of the main program to process DOT files in the Graphviz package.

ggplot2 Data visualization package for R

ggplot2 is an open-source data visualization package for the statistical programming language R. Created by Hadley Wickham in 2005, ggplot2 is an implementation of Leland Wilkinson's Grammar of Graphics—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a number of defaults for web and print display of common scales. Since 2005, ggplot2 has grown in use to become one of the most popular R packages.
