Show a DotPlot for when the duplication validation fails

[IsmailM]

When the wilcoxon test suggest that a sequence has been duplicated, it may be useful to show users a Dotplot (i.e. a sequence against itself). This would inform users in a highly visual manner, the region of the sequence that is duplicated and the rough percentage of the sequence that has been duplicated.

In order to avoid noise in DotPlot, one could simply use a window size equivalent to the duplicated region.

By DotPlot - I'm referring to something like:

This was produced by Dotter

agreed (but could be shown in all situations) - much like our other graphs.
maybe the biojs folks have a good dotplot library?

+1.

I did a quick search through BioJS registry and didn't find anything relevant. @IsmailM what would it take to do dot-plots in the browser? I'm interested in this for SequenceServer as well.

(I'm sure there are other webby implementations (I remember seeing one from a german group 2-3 years ago... but forget the name) - we should not reinvent the wheel here)
