Information visualization is essential in making sense out of large data sets. Often, high-dimensional data are visualized as a collection of points in 2-dimensional space through dimensionality reduction techniques. However these traditional methods often do not capture well the underlying structural information, clustering, and neighborhoods. GMap is an algorithm that turns these information into geographic maps, which are intuitive to most people. Using GMap algorithm and the OpenLayers library for map navigation give an interactive system for exploring the landscape of relations.
Map of TVs is based on aggregated and anonymized TV viewing data.
