A web-enabled Geovisual Analytics tool applied to OECD Regional Data [article]

Mikael Jern, Monica Brezzi, Lars Thygesen
2009 Eurographics State of the Art Reports  
In this paper, we introduce "OECD eXplorer" – an interactive tool for analyzing and communicating gained insights and discoveries about spatial-temporal and multivariate OECD regional data.  ...  Many approaches and tools have been developed in spatial-related knowledge discovery but generally they do not scale well with dynamic visualization of larger spatial data on the Internet.  ...  Each OECD region is represented by a string passing through the parallel axes. Each axis represents a single indicator in the data cube.  ...
