Spring embedder preprocessing for WWW visualization

P. Mutton, P. Rodgers
Proceedings Sixth International Conference on Information Visualisation  
We present a preprocessor for the spring embedder graph drawing method and show its use in speeding up the automatic layout of three-dimensional visualizations of WWW sites.  ...  Spring embedding is a widely used method for visualizing the connections in WWW maps, as it can typically produce a reasonable layout for most general graphs.  ...  Section 3 gives comparative results of using our method against using spring embedding without preprocessing and also shows the visualization of WWW sites with our method.  ...

Visualizing weighted edges in graphs

P. Rodgers, P. Mutton
Proceedings on Seventh International Conference on Information Visualization, 2003. IV 2003.  
The heuristic can be used in combination with the spring embedder to produce a compromise between a drawing with an accurate presentation of edge length and a drawing with good general comprehensibility  ...  This is related to previous research [6], where we found that the spring embedder was made more efficient by a preprocessing step consisting of an earlier version of the edge length method.  ...  A widely used method for drawing graphs with proportional edge lengths is to apply a metric spring embedder to the graph.  ...

Visualizing Set Data with the Metro Map Metaphor

Markus Wallinger, Martin Nöllenburg
2020
Using the metro map metaphor for set visualization could offer a functional middle ground between readability and scalability.  ...  Finally, we show how to perform post-processing for adding labels and minimizing line crossings in the drawing D.  ...  To achieve this two weights for scaling the forces are used. α mag is the weight factor for the magnetic forces and α spring is the weight factor for the spring-embedder forces.  ...
