Interactive tree
The interactive tree is a graph where the user is asked to answer questions regarding the challenge they seek to tackle and its characteristics by clicking on the equivalent visual elements. The interactive tree view allows the user to explore different paths rapidly and visualizes the many possibilities. Exploring the tree in this view can assist the user with understanding how certain (early) choices give direction to the proposed solution for various scenarios.
More specifically, the elements in the tree are:
- Rectangular: A question and nodes that link it to the possible answers. The text contains a question mark element that when hovered over pops up a window where the question in hand is explained.
- Rhombus: A possible answer. This element is clickable and the user can hence select an answer. Some of the answers can also be hovered over to produce pop-up explanations. When an answer is selected, the next question in the path is revealed.
- Rectangular with rounded edges: A decision on the PET technology based on the traversed path. The text contains a question mark element that when hovered over pops up a window where the decision is explained.
The other buttons seen on screen are:
- Toggle style: Choice to change colors.
- Toggle contrast: Choice to shift to black and white view.
- Expand tree: Choice to see the entire tree with all possible paths.
- Collapse tree: Choice to collapse the tree, i.e. reset the path.
- Auto collapse alternative routes: When selected, alternative routes automatically collapse when a different route is selected.
