There needs a way adjust color scheme in the matrixes. A short term
solution would be something that set color schemes globally for the
Toolkit(which would be nice to have anyway) but it needs to be in the GUI
somehow.

Perhaps you could provide a better form of "visibility of system status" as
described by Nielsen. When loading the data, perhaps the cursor should
change to an hourglass or other icon that indicates the system is
processing something.

For future work, I think it would be really helpful to allow users to scale
the starplots by a sum of multiple variables, or average of them perhaps.
For example, if I show fatalities for several time periods, it makes nice
little starplots that are ordered by time, and I pick out patterns there,
but then they often are not what they seem because each axis of the starplot
is being calculated relative to each particular variable. So for something
like fatalities it's a little difficult to understand because it might look
really high on one part of the starplot, but in actuality, the number of
fatalities is lower during that period than subsequent periods - it just so
happened that it was *relatively* high during that time period. Since there
are great reasons to use a starplot that always scales each axis
independently, it should be some sort of optional feature.

The code for MultiFrom Small Multiples is in the codebase, but it is not
exposed in the GeoViz Toolkit. I need to test it, add it to the GUI, and
add a marshal/unmarshal class for it.

Rob's comment:
Attached is an example of the "smart search box" I was describing. It is
basically a drop down menu with an input text box rather than a button or
icon. Each character you enter calls a function to research the array of
strings associated with the drop-down, eliminating ones that do not have a
character match. This could possibly be a quick solution for next Friday
to allow for filtering of variables by attribute and date:

Frank's comment:
Yes, this should be fairly easy. Prefuse features such a component (using
the Lucene engine), so we can just nab that one. The thing that is better
about the "smart search box" that Rob showed us that is even nicer, is that
his searches for matches anywhere in the search terms, but the Lucene
implementations I have seen match from left to right only, so, for example,
typing "Bay Marsh" would match "University Bay Marsh" in Rob's tool but not
in Prefuse. But that can be fixed, of course!

Create a graph type that creates small multiples, of maps or other data
views, with time on both axes. For example, year/month, or year/week, or
week/day. Map views and histograms would be good starter points.
Additionally, it would be good if other variables could be added in, either
in a fixed way (comparing all against one particular variable) or in each
time slice.

I also think it would be awesome to incorporate wikipedia or something
similar to this particular application. I often encounter deaths in some
place that seem unusual to me, and I want to learn more about why so many
died in the 70's in Peru or whatever. It would be very neat if something
akin to the question output that Geojunction can provide (a simple sentence
that summarizes what the user has done recently - a time range, filtered
based on geography, about a particular subset of variables - so "1970-1975,
Columbia and its neighbors, related to fatalities and attacks") could be
sent to wikipedia to see what it finds.

Can't remember if I already posted this, but... When a user wants to

causes an arbitrary unit (tract, county, whatever) to be selected and thus
displayed on the screen capture. Probably adding in key commands for the
save images toolbar would be best to work around this

In the maps, the star plots need to be scalable. Step one would be to have

In Alan's words:
the multi-select in the histogram is not Windows standard ... it seems that
CTRL click does not work and the SHIFT click works like CTRL click usually

In fact, this is an issue for many of the components in the GeoViz Toolkit.
I will prioritize the map and histogram for now.
