2. Describe the high level model (or framework) of the visualization to be designed. The model will show the main characteristics of the visual data processing.
a. Briefly describe the cycle of visual data processing with your proposed model.
3. Specification of the design of visualization. If using force-directed method, then describe the layout technique to be used for graph drawing.
a. Layout design specification, including (but not limited) the following details:
i. How to deal with the edge-crossing problem (if using a node-link diagram),
ii. How to deal with the objects node-overlap problem,
iii. How to enhance the readability of the layout,
iv. Labelling techniques.
b. Graphics design specification, including (but not limited) the following details
i. Graphic objects design,
ii. Graphic attributes design (and partitioning),
iii. How to map domain-specific attributes to graphic attributes
iv. How to address the data scale problem, particularly in dealing with the computational cost for running a selected layout algorithm
v. How to enhance the readability of domain-specific attributes
4. Specification of the design of an associated navigation scheme that includes the viewing scheme and interaction scheme
a. View Transformations specification, including (but not limited) the following details:
i. In-between views design and transformation algorithm,
ii. Animated viewing algorithm, if it is involved (optional)
iii. Human cognition process consideration during view transformations.
b. HCI design specification, including (but not limited) the following details:
i. Evaluate the efficiency of selected navigation mechanism by using Fitts's law and a usability study.
