[R] suggestions for plotting 5000 data points

I have a collection of 5000 entries which represent the evolutionary
rates of 3 animals.
I would like to show the differences between the rates of all 3
animals and have tried using the function parallel (from the lattice
package) and pairs() function.
The parallel function would have been perfect save for the large
number of data (5000). The pairs() function doesn't show the
difference explicitly. Does anyone have any suggestions on
representing such data or have done similar plots?
I attach some simulated data:
mat3 <-matrix(sample(1:5000),nrow=5000,ncol=3, byrow=TRUE)
colnames(mat3) <- c("human","mouse", "chicken")
mat2$model <- factor( rep( "Model 3"), labels="model3")
## code I used for parallel
parallel( ~ mat3[1:3]|model , mat3,varnames = c("human\ndnds", "mouse
\ndnds", "chicken\ndnds") )
any suggestions or pointers would be greatly appreciated.
