Data visualisation is a powerful tool to help non-statisticians understand and analyse large quantities of data. Probabilistic methods for projecting high-dimensional data to a 2d visualisation space, such as the Generative Topographic Mapping, are now well established in practical use. In this talk I will discuss how the basic algorithms can be enhanced to provide more information. Interactive tools help users interpret and drill down interactively into their data; block-structured covariance allows for the incorporation of prior understanding of relationships between variables; and technical improvements in the learning process allow us to better capture complex non-linear structure. These (and other new features) will be illustrated on a range of applications, including human obesity measurement, geochemical data for oil exploration, and analysis of small ligands for pharmaceuticals.
