See below for examples. Moreover teams I have worked with are often only interested in snapshots of the network diagram so the ability to plot network diagrams on dashboarding tools such as Tableau would offer greater convenience in highlighting significant findings where interactivity with the graph is less crucial. If you want to know more about this kind of chart, visit data-to-viz.com. Since this post is a snapshot in time. However due to the output format when a single node is filtered the links of the nodes are not filtered by default, this leaves many suspending links in the diagram: The solution I came up with was to generate an extra field known as [Link Id], which basically concatenates the [Id] of the source node and the [Id] of the target node.
