circular map software

[Neil Saunders]

Does anyone know what software is used to produce those circular chromosome
maps that we see in all the microbial genome papers?  I'm thinking of the
colorful things with concentric circles showing ORFs, tRNAs etc.  Had a look
through some genome papers, but couldn't see a reference.  Would this be
proprietary software, commercial, free?

thanks for suggestions,

Neil Saunders
