Graph Visualization Design (40%) – 32146 DVVA
This assignment requests each student to design a graph visualization to satisfy a list of specific
user’s requirements. In the design, students are required to select an appropriate graph layout
method and to create a set of optimized graphical properties that are mapping to a set of data’s
domain-specific attributes for better readability and understanding of the relational data
structure as well as six data’s attributes. This mapping is called as "attributed data
visualization", or infographics design, or figurative visualization.
You are also required to design a particular navigation scheme that includes the viewing
scheme and interaction scheme. Each student is required to submit a Design Report to address
the following questions. The weight of Design Report is 40%.
Note that this design includes (only) the design of "Visual Transformation (or Visual
Mapping)" and the design of "View Transformation (or Navigation)", according to the above
diagram.
General Requirement:
You are required to design a graph (network) visualization of the "flights” data as shown below.
The expected visualization can clearly show not only the flight's <From -> To> relational
structure, but also the other properties (attributes) associated with each flight.
Furthermore, this new visualization should be cooperated with a efficient navigation (browsing

or zooming) mechanism to enable users to view the detail of a particular focusing area of the
visualization. For example, through the navigation, the user could be then able to see the detail
of domain-specific attributes of a "flight" behind the infographics.
The Dataset
This flights dataset is not only a "relational" dataset, but also a "multidimensional" dataset. Of
course, we could simply use the parallel-coordinate visualization to represent this dataset, while
use the polylines to represent the <From -> To> relationships. The Figure below shows such
type of the visualization:
Obviously, this polyline-based network visualization does not achieve the high readability. It
contains too many edge-crossings or visual clutts. Therefore, we need to use the traditional
graph visualization methods to show the <From -> To> relationships, while to apply
"attributed data visualization" methods to show the domain-specific attributes of data itself.
Detailed Specification:
1. Select a graph visualization metaphor that you believe is most appropriate to be used
to represent the flights data. Providing support statement (or arguments) to convince
others about your selection. (4%)
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.
(4%)
3. Specification of the design of visualization. If using force-directed method, then
describe the layout technique to be used for graph drawing. (2%)
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), (2%)
ii. How to deal with the objects node-overlap problem, (2%)
iii. How to enhance the readability of the layout, (2%)
iv. Labelling techniques. (1%)
b. Graphics design specification, including (but not limited) the following details
i. Graphic objects design, (1%)
ii. Graphic attributes design (and partitioning), (4%)
iii. How to map domain-specific attributes to graphic attributes (2%),
iv. How to address the data scale problem, particularly in dealing with the
computational cost for running a selected layout algorithm (2%)
v. How to enhance the readability of domain-specific attributes (2%)
4. Specification of the design of an associated navigation scheme that includes the
viewing scheme and interaction scheme. (2%)
a. View Transformations specification, including (but not limited) the following
details:
i. In-between views design and transformation algorithm, (2%)
ii. Animated viewing algorithm, if it is involved (optional), (2%*)
iii. Human cognition process consideration during view transformations.
(3%)
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. (3%)
* Note that there are 5% bonus marks to the optional requirements.
