A good tool for gene locus visualization Does anyone know of a good tool for visualizing gene loci? Basically, I'd like to show how a group of genes look in different strains of a bacteria. I have annotation of course, I just need a tool to plug it into and get an image of the locus to compare.

I'm talking something basic like this:
I think in R, Gviz is the best choice. I have used it for human sequences but it will probably also be suitable for Prokaryotes.

Another option is MS powerpoint, if you only need the arrows...
