| An organization studying chemistry of the ocean
water in different parts of the world compares concentrations of 9 chemical
compounds found in each probe and performs additional analysis if they turn out
to be significantly different. |

By switching
NovoSpark Visualizer to
the "Identify Data Clusters" mode and loading chemistry data from different
areas as separate datasets the researchers can visually determine whether the
water probes differ from each other or are fairly similar. For instance, the
screenshot below clearly demonstrates that the two samples taken in
Atlantic
and
Pacific
oceans show up as two separate data clusters, so it is easy to conclude
that the water chemistry in these regions is not the same.

The Front View projection is used for further investigation of differences
between data clusters and individual observations within a single cluster. The
following screenshot shows that the observation curves in the two groups differ
from each other, and even some observations within the orange cluster are
slightly different from the others belonging to the same group.
