Graph Builder is a Java program for constructing graphs. It currently supports undirected, directed, and structural graphs. Additionally, the “Grid Graph” selection allows for creating graphs where node positions are locked on to a grid. The following graph statistics are maintained as the graph is constructed.

• Node count (int)
• Edge count (int)
• Connected (bool)
• Smallest and largest degree (int)
• Average degree (float)
• Smallest and largest geodesic (int)
• Average geodesic (float)

Additionally, the list of each node’s neighbors is maintained.
