Part 2 Help: Quality Considerations for Linking Data

Scalability for # items

• How many items can be linked for one relation?

Scalability for # relations

• How many relationships can be shown at the same time?

Perception issues

• Can the links be perceived easily or “preattentively”?
• Can all entities belonging to a relationship be easily identified?

Occlusion issues

• Is the base representation preserved?

Compatibility to base representation?

• Is the choice of visual encoding for a link suitable for the encoding of the base representation?

Practical/Implementation issues?

• Easy to implement?
• Efficient to implement?
