What? Multivariate Network Exploration and Presentation: Why? From Detail to Overview How? via Selections and Aggregations Stef van den Elzen Who? Jarke J. van Wijk When? Infovis – Nov 11, 2014 presented by Francisco Escalona Huh?
Multivariate Network Example: Census data by county of USA Nodes (also edges)
Filter Detail Overview Selec- tion 4 linked juxtaposed views: DOSA
Presentation Exploration task task
Adjustable 2D projection of nodes
Selection: boxes, ranges
Within
Between – color map
Background
Combined
Overview • Manual layout • Scatterplots, parallel- coordinates, histograms, treemaps, small multiples • Zooming • Aggregation
Migration in highly populated counties
Scale • 5-10 selections (2-6 expected) • 1-2 dozen attributes • 100s-1000s of nodes • more with aggregation • L < 4N
Strengths • Both network exploration and multivariate analysis • Intuitive, easy to use (?) • Dynamic exploration, visual querying • Can be used by novices • Expressive • Time • Topology
Limitations • Partitions only by nodes • Only supports ranges • Limited scaling up • No help on where to start • Overview can be too summarized • Axis can be difficult to see • One tool in a toolkit
In Summary A tool for exploration and presentation of multivariate network data using selection and aggregation in juxtaposed linked views
