Graphics (and other objects) are interactive in a much
more general sense in V6. While the simple default
interactivity of Graphics that you describe is gone,
it is very easy to roll your own.
Here's a simple little function called
labeledPointPlot:
labeledPointPlot[g_Graphics] := Manipulate[Column[{
Show[{g, Graphics@Point[pt]}], pt}],
{pt, Sequence @@ Transpose[PlotRange /. FullOptions[g]],
Locator}];
labeledPointPlot accepts a Graphics object and
returns a Manipulate which does what you want.
For example:
labeledPointPlot[Plot[x^2, {x, -2, 2}]]
Manipulate accepts a large number of Options which
allow you to control the appearance. At a more
fundamental level, the output of Manipulate is
defined in terms of more fundamental objects
called Dynamic primitives. These are analagous
to Graphics primitives generated by Plot and
related commands. If you are willing to work
at the level of Dynamics primitives, then you
have a tremendous amount of control over
beheavior and appearance.
