About

Graphia is designed and built by a small group working in Edinburgh, UK. We are passionate about graphs, the power of visualisation and creating tools that aid the interpretation of complex data.

Our journey started 20 years ago, as we began to envisage how graphs could help us analyse the relationships between genes and proteins. Over this time we developed multiple tools and refined our approach, eventually arriving where we are today with Graphia. We believe it is the best option for interactively visualising large graphs.

Pre-release Builds

Pre-release builds are available. Stability is not guaranteed, but any testing undertaken is greatly appreciated.

Building

Graphia uses the CMake build system. A full build can be performed using the following command:

cmake -B build && cmake --build build --parallel

Note however that you will usually also need Qt 6 to be installed and indicate to CMake where it lives:

CMAKE_PREFIX_PATH=/example/path/to/Qt/6.5.0/gcc_64/ cmake -B build && cmake --build build --parallel
