Tabnetviz - table-based network visualizer
Tabnetviz generates network visualizations from node and edge properties provided in tables. The node and edge properties can be mapped to visual attributes in several ways. Tabnetviz was inspired by the popular Cytoscape program which can also generate similar mappings. However, Cytoscape is a resource-intensive, interactive Java program with a complex graphical interface, and loading networks from tables and defining mappings can be cumbersome in it. Tabnetviz, on the other hand, is a non-interactive, lightweight command-line tool guided by a single text-based configuration file, thus ideal for use in scripts, Makefiles, and reproducible workflows. Once a configuration file has been developed, it only takes a single command to generate the network visualization (typically an SVG file), and to quickly regenerate it whenever the input data changes.
Tabnetviz generates static network visualizations, and is applicable in a wide range of fields such as bioinformatics (for gene regulatory networks, protein interaction networks, etc.), neuroscience, and studies of social networks, computer networks, economic networks, etc.
The Tabnetviz configuration file is a YAML format text file, which is easily written manually, and easy to understand. It specifies the node table and the edge table for the network (both can be CSV, TSV, or Excel files), and defines how to map the node and edge properties (provided in node and edge table columns) to visual attributes such as colors, node sizes, shapes, line widths, etc. Node groups and edge groups can also be defined (using Boolean expressions on the node/edge properties), and the mappings can be applied to them.
Tabnetviz is a Python program, and uses Graphviz as its network visualization back-end, and can use any node, edge, and graph attribute known to Graphviz. It also uses Graphviz for generating network layouts. Relying on the power of Graphviz, Tabnetviz can generate high-quality images suitable as illustrations for science publications.
As a bonus, Tabnetviz can optionally calculate numerous graph theoretical quantities such as degrees, centralities, clustering coefficients, etc. These are added to the node/edge table, and can then be mapped to visual attributes, e.g. node sizes or colors.
Tabnetviz uses Python 3.2+. Once you have Python installed, you can install Tabnetviz by
pip install tabnetviz
pip3 if you have separate “pip”s for Python 2 and 3).
Alternatively, you can download the source distribution from github.
(Note that sometimes
pip cannot install
pygraphviz (required for
tabnetviz) correctly because of a compilation error. In this case,
you may try to install it in another way. On Debian Linux, use
install python3-pygraphviz, or
apt install libgraphviz-dev before
pip. See this

A configuration file template can also be output from the program
--configtemplate option; this can be used as a start for
writing a configuration file for your visualization.
Tabnetviz uses Python 3.2+ and requires the following Python modules to be installed: PyYAML, yamlloader, pygraphviz, pandas, matplotlib, networkx, svgwrite.
