versinus

Versinus: a visualization method for time-evolving networks

documentation

Current best documentation is the article in the doc/ directory, and the resources in this repository.

There is also a dummy and less recent article available in arXiv: https://arxiv.org/abs/1412.7311

implementations

Versinus was conceived while probing stability of social networks and was found to be very useful. It has since then received four implementations:

• a Python script that renders animations though stop-motion, available in legacy/sistemaMinimo_5000Py3.py
• Python functionalities made available though packages. These packages enable the rendering of animations with soundtracks, both obtained by mapping of the evolving network. The packages needed are gmaneLegacy and musicLegacy. After installing them, run the script tests/testEvolutionMusicPy3.py in the gmaneLegacy tree.
• a lightweight Javascript implementation in ccNetViz for static networks.
• a Javascript implementation for interactive data visualization: https://github.com/ttm/netText.

available videos

Some animations obtained using the Versinus method (and the scripts mentioned above) are available in the following playlists:

further info

To render the stop-motion animations, you may use ffmpeg. E.g.: $ ffmpeg -r 25 -i "%05d.png" versinus.mp4

And use ffmpeg again to add the sound track: $ ffmpeg -i video.avi -i audio.mp3 -codec copy -shortest versinus.avi
