Examples at the link below illustrate interactive charts created with the googleVis package and R.

Some amazing features are: a motion chart shows the changes over time, an AnnotatedTimeLine shows zoom-in/zoom-out view of time series, a TreeMap supports drill-down and scorll-up (with left/right-click), a Geo map is very easy to generate, and multiple charts of different types can be merged into one panel.
More examples are available by running “demo(‘googleVis’)” in R, after the installation of the googleVis package.
