The network waterfall graph is showing a timeline view of HTTP requests. This is useful. 

Another useful view is a dependency graph, specifically in these days, where HTTP requests are deeply nested. To illustrate, let's say you query

http://example.org/
it then loads the HTML which in return will call some CSS, JS, and images.
then these CSS, JS will probably call other CSS, images, JSON and JS and so on. At the end you end up with a graph of HTTP Requests. 

When a JS calls another JS which calls another JS, etc… and fails. It can become very handy to understand the "follow your nose" path of HTTP requests, so you can debug why a script didn't execute or data are missing because they were never requested higher up in the graph.
