[Bioperl-l] graphics of gene distribution through a genome interval

[Carnë Draug]

Hi everyone

I was wondering if anyone knows any tools to produce this type of
diagram? http://picpaste.com/1fqB4e8h.png It a piece of genome with
some gene positions marked. And it has nice "zoom-in boxes" around
some more cluttered regions. I've seen these more than once but do not
know how to generate one. Could someone give me a pointer?

Thanks,
Carnë
