This package provides a library for the analysis of networks and graphs. It can handle large graphs very well and provides functions for generating random and regular graphs, graph visualization, centrality methods and much more.

This package provides an implementation of the function bioFabric for creating scalable network digrams where nodes are represented by horizontal lines, and edges are represented by vertical lines.

plantri and fullgen (contained in the same package) are programs for the generation of certain types of planar graphs. Graphs are generated in such a way that exactly one member of each isomorphism class is output without the need for storing them.

This package provides a library for the analysis of networks and graphs. It can handle large graphs very well and provides functions for generating random and regular graphs, graph visualization, centrality methods and much more.

Faiss is a library for efficient similarity search and clustering of dense vectors. It contains algorithms that search in sets of vectors of any size, up to ones that possibly do not fit in RAM. It also contains supporting code for evaluation and parameter tuning.

rw computes rank-width and rank-decompositions of graphs.

Faiss is a library for efficient similarity search and clustering of dense vectors. This package provides Python bindings to the Faiss library.

Graph-tool is an efficient Python module for manipulation and statistical analysis of graphs (a.k.a. networks). Contrary to most other Python modules with similar functionality, the core data structures and algorithms are implemented in C++, making extensive use of template metaprogramming, based heavily on the Boost Graph Library. This confers it a level of performance that is comparable (both in memory usage and computation time) to that of a pure C/C++ library.

This package provides a pure Python implementation of the Louvain algorithm for community detection in large networks.

QVGE is a multiplatform graph editor written in C++/Qt. Its main goal is to make possible visually edit two-dimensional graphs in a simple and intuitive way.

The PyGSP is a Python package to ease signal processing on graphs.

This package implements the Louvain algorithm for community detection in C++ and exposes it to Python. Besides the relative flexibility of the implementation, it also scales well, and can be run on graphs of millions of nodes (as long as they can fit in memory). The core function is find_partition which finds the optimal partition using the louvain algorithm for a number of different methods.

Mscgen is a small program that parses Message Sequence Chart descriptions and produces PNG, SVG, EPS or server side image maps (ismaps) as the output. Message Sequence Charts (MSCs) are a way of representing entities and interactions over some time period and are often used in combination with SDL. MSCs are popular in Telecoms to specify how protocols operate although MSCs need not be complicated to create or use. Mscgen aims to provide a simple text language that is clear to create, edit and understand, which can also be transformed into common image formats for display or printing.

Leiden is a general algorithm for methods of community detection in large networks and is an extension of the Louvain algorithm. This package implements the Leiden algorithm in C++ and can be run on graphs of millions of nodes (as long as they can fit in memory).

This package implements the Louvain algorithm for community detection in C++ and exposes it to Python.

This package contains OpenXR headers, as well as source code and build scripts for the OpenXR loader.

This package provides a common standard tangent space library used in baking tools to produce normal maps.

Skia is a 2D graphics library for drawing text, geometries, and images. It supports:

• 3x3 matrices with perspective

• antialiasing, transparency, filters

• shaders, xfermodes, maskfilters, patheffects

• subpixel text

GR is a universal framework for cross-platform visualization applications. It offers developers a compact, portable and consistent graphics library for their programs. Applications range from publication quality 2D graphs to the representation of complex 3D scenes. GR is essentially based on an implementation of a GKS. As a self-contained system it can quickly and easily be integrated into existing applications (i.e. using the ctypes mechanism in Python or ccall in Julia).

Flux is an interface description language used by DirectFB. Fluxcomp compiles .flux files to .cpp or .c files.

The OpenSceneGraph is a high-performance 3D graphics toolkit used by application developers in fields such as visual simulation, games, virtual reality, scientific visualization and modeling.

OpenVDB is a C++ library comprising a hierarchical data structure and a large suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It was developed by DreamWorks Animation for use in volumetric applications typically encountered in feature film production.

Drawpile is a drawing program that allows share the canvas with other users in real time.

Some feature highlights:

• Shared canvas using the built-in server or a dedicated server

• Record, play back and export drawing sessions

• Simple animation support

• Layers and blending modes

• Text layers

• Supports pressure sensitive Wacom tablets

• Built-in chat

• Supports OpenRaster file format

• Encrypted connections using SSL

• Automatic port forwarding with UPnP

MangoHud is a Vulkan and OpenGL overlay for monitoring frames per second (FPS), temperatures, CPU/GPU load and more.
