Create a Network Graph

To create a network graph:
  1. Make sure that both the node and link data sets have been loaded. For instructions, see Load Data into SAS/GRAPH Network Visualization Workshop .
  2. Select Graphsthen selectVisualize Network, and then select a layout pattern from the cascading menu. For descriptions of the layout pattern, see About Network Graphs . Note the following:
    • If you chose the Fixed Position layout style, then you are prompted to open a positions file and to specify which variables in the file correspond to the X and Y axes. For information about the positions file, see Creating a Positions File for a Fixed Position Network Graph .
    • If you haven’t already specified the link and node attributes (the FROM, TO, and NODE ID variables), then the Edit Data Attributes dialog box is displayed. For help with this dialog box, see Specify Data Attributes .
You can fine-tune the layout pattern by adjusting the layout algorithm used for the graph. For details, see Layout Tab .
