Interaction
“Interaction involves the transformations that map the data to visual form.”
More than just controls? Integrates controls into the visualization.
Allows for direct manipulations of the graphical representation of the data.
Examples
Ahlberg & Shneideman, The Film Finder
Chuah et al., SDM
Ware, Chapter10, Information Visualization
Munzner,H3

High Interaction Graphics
ClarityInformation only on demand, cleaner & more focused displays, allow a range of options
RobustnessAvoid drawing inferences from only one view
PowerCombine views, leverage exploration
Possibility3+ dimensional data, animation
Principles
Simple, easy to interpret views Information Hiding Direct Manipulation Linking & Brushing
Linking and Brushing
Linking Visually showing which parts of one data plot
correspond to that of another. Brushing
Allowing the users to move a region (brush) around the data display to highlight points which fall within this region.
Slide adapted from Marti Hearst
Examples
Districts of the city of Dublin showing areas with high levels of average income
Linking altitude to grass and grain types in Scottish Districts
Critique
Pros: Very good survey paper for introduction, general
techniques. Easy to read. Seems like the beginning of a book.
Cons: Examples were somewhat simple, despite
mentioning some complex application domains. Dated. Open issues are easy nowadays.
