Materials for the PyData Barcelona 2017 workshop on Network Analysis with Python and NetworkX.
Social Network Analysis (SNA) has a wide applicability in many scientific fields and industries. This workshop is a gentle introduction to SNA using Python and NetworkX, a powerful and mature python library for the study of the structure, dynamics, and functions of complex networks. Participants in this workshop should have a basic understanding of Python, no previous knowledge of SNA is assumed.
For this workshop attendees will need to install NetworkX (>=1.11), Matplotlib (>=1.5), numpy (>=1.10) and have a working Jupyter Notebook environment. Some examples will also use Pandas (>=0.17) and Seaborn (>=0.7), but these packages are not essential. Only basic Python knowledge is assumed.
