- Abstract:
-
We introduce nonlinear magnification fields as an
abstract representation of nonlinear magnification,
providing methods for converting transformation routines
to magnification fields and vice-versa. This new
representation provides ease of manipulation and power
of expression. By removing the restrictions of explicit
foci and allowing precise specification of magnification
values, we can achieve magnification effects which were
not previously possible. Of particular interest are
techniques we introduce for expressing complex and
subtle magnification effects through magnification
brushing, and allowing intrinsic properties of the
data being visualized to create data-driven
magnifications.
