Adding attributes to an element is as easy as calling theattrmethod. Nodes and connections are defined separately so that nodes can be reused and connections can be quickly changed. We now have our four parts (CSS, D3, javascript graph, and Data) that are required to build the chart. Then, we can addthe properties that we expect these Nodes to have: However, linking between Nodes in this manner is verbose, causing the Diagram to become too large.
