Imagine having an important message that needs to reach an entire group (for example, your employer or school), but only being able to give that message to one person. Who would you tell? You'd want to find someone well-connected to the entire network. You might try the person with the highest degree centrality (the most friends). The downside to that approach is that their friends might not be well connected to the rest of the network. In a hypothetical company, for example, the Director of East Coast Sales might know the most people, but might not know how to reach anyone in other departments or regions. Instead, it would be better to find someone who is highly connected to other highly-connected people, such as the CEO (or, more likely, their assistant). Such individuals are sometimes called hubs, because, like the center of a spoked...

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.
