3 Kurt Jacobson Mark Sandler 2009 Web Science Athens, Greece WSRI 1 1 17/03/2009 In an effort to move towards intuitive visual interfaces for faceted browsing of structured data about music, we develop a visualization technique called k-pie}. Derived from a network visualization technique know as $k$-cores decomposition, k-pie layout accounts for the semantic labels or `colors' associated with each vertex. Vertices of a graph are arranged in a 2 dimensional circle where `slices' in the circle correspond to a specific vertex label and the most connected vertices are found in the center of the visualization. We describe the k-pie algorithm and demonstrate how it can be useful in the context of Semantic Web technologies. http://journal.webscience.org/110/
