- Stage 2 Tutorial with Sample Task

**Some Graphs of Linked Entities (optional output of the SimpleGraph Gaze-Link algorithm) **

The graphs show the visual path of exploration. Entities that are placed closer together have stronger links between them and in turn with the task at hand.

Three graphs are shown below for task 1, 4, and 5 respectively. The graph for task 4 is an example of a very direct graph where the developer knew exactly where to find the answer. The graphs for Task 1 and task 5 have more interesting shapes. Task 1's graph (and Task 4's graph) shows a linear progression. Task 5's graph shows two different paths taken by the developer to solve the problem.
