Nested Models
Domain |
Understand the user, the data and tasks |
| |
Use domain specific vocabulary |
| |
Produce a set of tasks/questions of target users on the data, on different levels |
Data/task abstraction |
Data described in generic (Visualization) terms |
| |
Tasks described in generic (Visualization) terms |
Visual encoding/interaction idiom |
Design space, select visual encodings, define interactions, etc. |
Algorithm |
layout algorithm, ordering, rendering, etc. |
Dangers at each level
A mistake at the higher level cannot be corrected on the lower
