We've used that as a term to describe the plotting of data
that uses different coordinates than what was provided.
In information visualization as opposed to scientific visualization or
other domain visualization where the data comes to you in a more concrete metaphor,
information visualization the information is much more abstract, and so
the challenge is going to be being able to take that abstract information and
find a concrete metaphor to communicate it to the viewer, so
it can be more easily understood.
The second is large data visualization.
We often hear of big data and there's also big data visualization.
The focus of big data or large data visualization is sometimes just on
the computation mechanics of handling large data sets.
But we're going to focus specifically on the visualization of large data, where
the data is so large that it's visually overwhelming if you display everything,
and so you have to be very selective about what you display so
that you can keep it mentally organized.
And so, we're going to depend on interactivity, the interactive aspect
of these visualization system to be able to, over time,
focus on certain elements of our visualization that we're interested in,
and to be able to ignore other elements so that these data sets,
which would be very large, don't overwhelm our cognitive understandings.
Third is visual analytics, visual analytics is an area that grew out of
business analytics and business intelligence, and
it's specifically on visualization, being able to look at data sets visually and
to be able to analyze them, draw conclusions from them,
and it focuses also on being able to make a decision based on data and
that decision is implied by the visualization, that the visualization
is giving you the insight in order to make a good decision based on your data.
And finally the goal of this week is to make a visualization dashboard.
We want to be able to organize the visualizations when we have multiple
visualizations and we have a lot of data.
We'll want to be able to produce a dashboard view that gives you everything
you need in order to be able to make a good decision based on the data.
