[kepler-dev] Vector GIS data Visualization Actor and High-Dimensional data PCP Visualization Actor

[Dan Higgins]

Matt & Jianting,
    I agree that it would be great if we had a shapefile visualizer in 
Kepler (some of the ENM group had requested such a feature for some 
future analyses.) The PCP feature is also useful. I did some research 
and found that there is an R function (in the MASS package) called 
'parcoord' that creates PCP plots, so we can also use the RExpression 
actor to create such visulaizations! (see attached figure)
