Figure 1. Diffusion of Smoking Initiation through the School 1 Friendship Network (N = 449).

Figure 1.

Note: Each node represents a student, and directed ties between nodes represent friendship nominations. Node color is based on lifetime smoking where yellow = initiated smoking in the time since the last observation, black = initiated smoking prior to the last observation, and white = have not initiated smoking. Isolates (nodes with no friendship nominations) are not included in the visualization (This figure appears in colour online).
