which can be accomplished in the visualization by looking at the type. which 
is, i suppose, why you asked for something like a getSourcesByProperty method. 
i'd prefer not to offer that as it is not generic enough: most visualizations 
have no need for it, and others would want/need something more complex. it's 
easier, for now at least, to just put such filtering in the visualization 
code.
