Chapter 3. Graph Analysis and Visualization
In this chapter, we will learn how to analyze the characteristics of graphs using visualization tools and graph algorithms. For example, we will use some of the algorithms available in GraphX to see how connected a graph is. In addition, we will compute metrics that are commonly used, such as triangle counting and clustering coefficients. Furthermore, we will learn through a concrete example how the PageRank algorithm can be used to rank the importance of the nodes in a network. Along the way, we will introduce new RDD operations that will prove out to be useful here and in later chapters. Finally, this chapter offers practical tips on building Spark applications that rely on the third-party libraries. ...
