A nested model for visualization design and validation

Note

4 layers nested model to analyze and evaluate the visualization design. The layers are:

1. Domain problem and data characterization: the designer should follow the "vocabulary" in each domain, e.g. business or biology.  
2. Operation and data type abstraction: data type transformation
3. Visual encoding and interaction design: the cost of interaction
4. Algorithm Design: run-time speed and time

To evaluation:

1. Vocabulary: to discuss the terminology in different domains
2. Interactive Loops and Rapid Prototyping: looping and refining. 
3. Domain Threats: mischaracterized problem
4. Abstraction Threats: not solve the characterized problem the target users.
5. Encoding and interaction Threats: not effective communication. 
6. Algorithm Threats: memory performance.
