Netwulf
Netwulf is an interactive tool that helps visualize NetworkX graph objects. It is user-friendly and can be utilized directly from Python or Jupyter Notebooks.
Ideal for research, Netwulf allows users to easily modify the appearance of networks. Users simply input a Graph object, experiment with the design, and then save the output as an image or continue manipulating it in Python. The focus here is on visual aesthetics rather than extensive coding.
nxviz
nxviz is a Python library that streamlines graph visualization using Matplotlib. It offers a straightforward method for creating visually appealing and informative graph representations. nxviz can produce various graph types, including Circos, Arc, Matrix, Hive, and Parallel plots.
- GitHub: https://github.com/ericmjl/nxviz
Py3plex
Py3plex is a Python library designed for exploring and visualizing complex networks. It allows users to break down, illustrate, and analyze networks with additional information on points or edges.
Py4cytoscape
Py4cytoscape brings Cytoscape functionality to Python, allowing users to switch between R and Python for network tasks without needing to learn a different syntax. It interfaces with Cytoscape through the web, providing a wide range of functionalities for use within Python or Jupyter Notebooks.
pydot
pydot serves as a Python interface for Graphviz, allowing users to parse and generate DOT language files used by Graphviz.
- GitHub: https://github.com/pydot/pydot
PyGraphistry
PyGraphistry is a Python library designed for visualizing large graphs. It streamlines data acquisition, manipulation, and visualization, all while maintaining high performance. PyGraphistry integrates seamlessly with Graphistry's powerful servers, allowing users to generate large-scale visualizations quickly.
Graphistry is particularly adept at rendering expansive graphs, thanks to its dedicated drawing engine capable of handling numerous nodes and edges simultaneously.
python-igraph
Python-igraph provides a Python interface to the igraph library, a robust tool for analyzing complex networks developed in C. It also supports integration with R, Mathematica, and C/C++.
Features of python-igraph include:
- Creating, manipulating, and analyzing networks.
- Converting graph data to formats compatible with NetworkX and graph-tool.
- Visualizing networks using Cairo, Matplotlib, and Plotly.
- GitHub: https://github.com/igraph/python-igraph
pyvis
pyvis is a Python library that facilitates the creation and visualization of interactive graph networks.
SNAP: Stanford Network Analysis Platform
SNAP is a versatile, high-performance framework for analyzing and managing large networks. It encompasses nodes and directed/undirected/multi-edges connecting them. In this context, networks are graphs enriched with data on nodes and/or edges.
The SNAP library, written in C++, is optimized for efficiency and generates high-quality network visualizations. It effectively processes large networks with numerous nodes and edges, analyzes their structures, creates new networks, and allows modifications during execution.
