One way would be to draw the logarithm of the traffic count:

L=log(1+C)

where C is the bytes/bits transferred and L is the variable to be plotted.
I think RRDTool is able to do these logarithmic plots. The one is added
in case the traffic is 0. In that case L becomes 0. If you have a 2Mbit
it might be nice to display

L2M=log(1+C*.5)

in that case the yscale will be:

L2M: 0  1   2    3   4    5    6
C    0 18 198 1.9k 19k 190k 1.9M 

Another neat way to do it is to use the base2 log...
