Network Graph Visualizations with DOT

Network graphs play a large part in both computing and data science, and they are essential for working with (and visualizing) both semantic graphs and property graphs. Nearly thirty years ago, AT&T produced a set of libraries called graphviz which were designed to generate various types of printed output. Over the years, the library has been adapted for different platforms and roles, and today is still one of the most widely used network graph visualization tools around. One of the most common libraries associated with graphviz is the DOT library. DOT is a declarative language that let's users specify the components of a network graph, including the nodes (or dots) that are typically used to represent entities, along with the directed edges that are used to specify relationships or attributes.
