Experimental Touchgraph (-like) Visualization

11. März 2009 – 21:13

David Decraene has played around to implement a TouchGraph like, but javascript-based, visualization of OWL data. He ist not using Canvas or SVG elements nor flash, just pure DOM-HTML manipulations. The result seems to be promising and attractive at the same time. If his visualization is supporting viewing standalone nodes (or group of nodes) it’ll be much greater than GraphViz, i’am using right now. The view is collapsible, browseable and dynamic — not using static generated (.png) views.

Before, David was trying to map OWL Data to a hyperbolic tree view based on the Javascript Information Visualization (JIT) Framework. While the Framework was easy to set up and the “the result is a quite cool ontology view“, David was not very pleased about the resulted view. He is blaming “the nature of hyperbolic tree visualizations, which only seem to work well if you visualize pure hierarchies (each node has one parent max)“.
