The location/mapping part is not so important. There are cases of small overlaps for some plots (ie figures) so I'm keen to write or find a function that moves my small scatter plots so they don't overlap. A little like jitter, but not random in behaviour, it needs to move away from the plots it's overlapping.

I would investigate the subplot() function in Greg Snow's
TeachingDemos package, possibly in conjunction with his
updateusr() function.

For interactive placement of figures, it should be possible to
use locator() to place each plot.
