Visualizing How Networks Change Over Time

Watching phenomena change over time is a big component of modern data science techniques and is the basis for time series methodologies. However, when it comes to networks, whether of people or something else, I don’t see a lot of work being done on understanding how they change over time. In this article – the last of my project based on the Friends TV series – I look at ways that you can create visualizations of changing networks using R (for more basic methods) and the Javascript D3 library (for more advanced methods).
