Spatial selections are a ubiquitous concept in visualization. By lo-
calizing particular features, they can be analyzed and compared in
different views. However, the semantics of such selections are of-
ten dependent on other parameter settings and it can be difficult to
reconstruct them without additional information. In this paper, we
present the concept of contextual snapshots as an effective means
for managing spatial selections in visualized data. The selections
are automatically associated with the context in which they have
been created. Contextual snapshots can be also used as the basis
for interactive integrated and linked views, which enable in-place
investigation and comparison of multiple visual representations of
data. Our approach is implemented as a flexible toolkit with well-
defined interfaces for integration into existing systems. We demon-
strate the power and generality of our techniques by applying them
to several distinct scenarios such as the visualization of simulation
data and the analysis of historical documents.
