Abstract :
Multidimensional projection techniques have experienced many improvements
lately, mainly regarding computational times and accuracy. However, existing
methods do not yet provide flexible enough mechanisms for
visualization-oriented fully interactive applications. This work presents a
new multidimensional projection technique designed to be more flexible and
versatile than other methods. This novel approach, called Local Affine
Multidimensional Projection (LAMP), relies on orthogonal mapping theory to
build accurate local transformations that can be dynamically modified
according to user knowledge. The accuracy, flexibility and computational
efficiency of LAMP is confirmed by a comprehensive set of comparisons.
LAMP’s versatility is exploited in an application which seeks to correlate
data that, in principle, has no connection as well as in visual exploration
of textual documents.

Abstract :
Clustering as a fundamental data analysis technique has been widely used in
many analytic applications. However, it is often difficult for users to
understand and evaluate multidimensional clustering results, especially the
quality of clusters and their semantics. For large and complex data,
high-level statistical information about the clusters is often needed for
users to evaluate cluster quality while a detailed display of
multidimensional attributes of the data is necessary to understand the
meaning of clusters. In this paper, we introduce DICON, an icon-based cluster
visualization that embeds statistical information into a multi-attribute
display to facilitate cluster interpretation, evaluation, and comparison. We
design a treemap-like icon to represent a multidimensional cluster, and the
quality of the cluster can be conveniently evaluated with the embedded
statistical information. We further develop a novel layout algorithm which
can generate similar icons for similar clusters, making comparisons of
clusters easier. User interaction and clutter reduction are integrated into
the system to help users more effectively analyze and refine clustering
results for large datasets. We demonstrate the power of DICON through a user
study and a case study in the healthcare domain. Our evaluation shows the
benefits of the technique, especially in support of complex multidimensional
cluster analysis.

Abstract :
We present MoleView, a novel technique for interactive exploration of
multivariate relational data. Given a spatial embedding of the data, in terms
of a scatter plot or graph layout, we propose a semantic lens which selects a
specific spatial and attribute-related data range. The lens keeps the
selected data in focus unchanged and continuously deforms the data out of the
selection range in order to maintain the context around the focus. Specific
deformations include distance-based repulsion of scatter plot points,
deforming straight-line node-link graph drawings, and as varying the
simplification degree of bundled edge graph layouts. Using a brushing-based
technique, we further show the applicability of our semantic lens for
scenarios requiring a complex selection of the zones of interest. Our
technique is simple to implement and provides real-time performance on large
datasets. We demonstrate our technique with actual data from air and road
traffic control, medical imaging, and software comprehension applications.
