What is the way to view a DGML file that is very big in Visual Studio?

One way to view a large DGML file in Visual Studio is to use the Graph View Layout feature, which allows the user to zoom in and out of the graph and navigate through it without losing context. To enable this feature, right-click on the DGML file in the Solution Explorer and select "Open With" -> "XML (Text) Editor". Then, locate the <graph> element in the file and add the attribute "Layout="Sugiyama"" to it. Save the file and reopen it in Visual Studio. The graph should now be displayed with the Graph View Layout feature enabled.
