Abstract
In this paper we present a novel approach to visualize ir-
regularly occurring events. We introduce the event line view designed
speci¯cally for such events data (a subset of time dependent data). The
event line view is integrated in a coordinated multiple views (CMV)
system and linked with other conventional views to support interactive
visual analysis. The main idea is to analyze events relative to two cat-
egorical attributes from a multidimensional multivariate dataset. Since
we are interested in the categorical dimension we have also integrated
and linked the tag cloud view in the CMV system. To the best of our
knowledge this is the ¯rst integration of the tag cloud view in a CMV
system. The tag cloud view can depict a ratio of the selected items versus
the non-selected items.
The proposed approach is illustrated using the VAST Challenge 2008
Geo-Spatial data set that contains data on interdiction or landing of ille-
gal immigrants in the USA. It is a multivariate multidimensional dataset
with irregular events that illustrates the potential and capabilities of the
proposed approach and the developed CMV system.
