Social networks are one of the most compelling applications of network science. From the early days of sociometry to the more recent social network analysis, concepts from network science have helped uncover insights about groups of people and how they interact. Tie strength can be used to find weak ties that predict how communities might split and that enable information to spread across distant regions of a network. Small world networks resolve the paradox of small paths across networks of local connections. All of these structural properties have important implications for contagions: the spread of things such as ideas and diseases across groups of people. The concepts learned in this chapter are crucial for understanding how people behave and interact in groups. If you liked simulating contagions in this chapter, you'll love the next one! It's all about simulating...

Overview of this book
NetworkX is a leading free and open source package used for network science with the Python programming language. NetworkX can track properties of individuals and relationships, find communities, analyze resilience, detect key network locations, and perform a wide range of important tasks. With the recent release of version 2, NetworkX has been updated to be more powerful and easy to use.
If you’re a data scientist, engineer, or computational social scientist, this book will guide you in using the Python programming language to gain insights into real-world networks. Starting with the fundamentals, you’ll be introduced to the core concepts of network science, along with examples that use real-world data and Python code. This book will introduce you to theoretical concepts such as scale-free and small-world networks, centrality measures, and agent-based modeling. You’ll also be able to look for scale-free networks in real data and visualize a network using circular, directed, and shell layouts.
By the end of this book, you’ll be able to choose appropriate network representations, use NetworkX to build and characterize networks, and uncover insights while working with real-world systems.
