distinction

is spatialization given (scivis) or chosen (infovis)

my infovis definition
interactive visual representation to help person do a particular task

infovis: how to represent
choosing, doing, evaluating
huge space of possibilities: random walk ineffective
need design guidelines, prescriptive advice

separation
now judged by different criteria	
divergence allows each field to expand/improve faster
room to explore before borders all tangled
