Animating Treemaps
M. Ghoniem & J-D FeketeEcole des Mines de Nantes
Why animate treemaps ?
When changing the weight attribute
e.g. from # of children to size of children
zooming in and out the tree is changing dynamically
The geometry may change a lotAnimation makes it possible to follow
the transition from one view to the other
Example
Main concerns
Visible continuity during the animation simple linear interpolation of the
geometry does not work!easy with slice and dice treemaps
Linear interpolation of the node weightsproblematic with squarified treemaps
Order is not maintained among siblings Chaotic jumps occur during the animation
Animation
Improving Continuity with Squarified Treemaps
Layout in Spiral order siblings turn instead of jumping
Problems taken individually, each level is easy to
follow as a whole, the animation is very
chaotic

Animating Squarified Treemaps
Work in progress
Improve continuity in animation level by level animation?
Experiment with other tree layout visualizations Sunburst Node Link Diagrams
