Focus Nodes is a Drill Down Graph PRO feature that allows you to choose which nodes are displayed in the initial view of the graph, and which nodes are collapsed by default. You can further customize focus node behavior with Initial Node Expansion Level and Node Expansion Radius settings in the Format Visual tab.

Use this field to assign a Focus Node status to the target node(s):

• 1: the target node(s) will always be displayed in the initial view.
• 0: the target node(s) won't be shown.
