### New features:

`rasterImage()`

(R2.11)- bitmap raster drawing;
- have maps as data backdrops.
- Polygons with holes:
`polypath()`

-(R2.12) - At present there is no way to tell when to actually show the plot. For example:
`plot(x); lines(x)`

. Should we display the plot after`plot`

or after`lines`

- Solution
`dev.hold()`

and`dev.flush()`

- Better performance and useful for animations – (currently in R-dev).

### Challenges

Data size increases, but large RAM (>100GB) and CPU power is affordable. Visualization needs to keep up.

- Currently rendering is slow. Solutions: OpenGL + GPUs.
- Visualisation methods for large data
- interactivity (divide and conquer, shift of focus): use iPlots eXtreme (very nice demo of iplots!)
- sufficient statistics, aggregations, etc.
