I have a list of human genes (order matters, since they have been clustered together) and I'd like to see their position in the genome.

I was thinking about something like this:

two axes one above the other;

first axis represent the genome displayed as one chromosome after the other;

second axis represent gene list with arrows pointing from each gene to the correspondent location in the genome.

Ideally, I hope to see groups of arrows pointing to the same location in the genome.

I think I won't have much difficulties in writing a script with R, but in order to spare some time, I was wondering if any package or tool already exists
