This code is what I used to make the visualizations of SocioPatterns' primary school data here
It requires the data of the same format described in SocioPatterns webpage: 1. A sorted list of contacts. 2. Each row has five numbers: time, id-1, id-2, node-type-1, node-type-2. 3. The node types are 11 class labels 1A, 1B, 2A, etc. and Teachers.
Furthermore, you need a special structure of the directories. If the raw data is called primaryschool1, then the input file needs to be in data/primaryschool1.txt, the raw output (PNG pictures of all frames) will end up in frames/primaryschool. These could be compiled to a MP4 by ffmpeg, and stored at clips/primaryschool1.mp4:
ffmpeg -r 48 -i frames/primaryschool1/%05d.png -vcodec libx264 -pix_fmt yuv420p -strict -2 -acodec aac clips/primaryschool1.mp4
