Visualize location of genes on Chromosomes

I'm trying to create a figure which visualizes the locations of NBS-LRR genes on chromosome 1 on the watermelon genome based on the watermelon sequencing genome paper here. Essentially, I want to create a chromosome map of locations of specified genes for a figure.

I've tried to set up the watermelon genome as a database for BLAST, and while it did give me the numeric location of these genes on the watermelon genome, it doesn't do a good job with "visualizing" where the genes lie on the chromosome.

I'm thinking about using bowtie to align these sequences to chromosome 1 and then visualizing their locations and alignment in IGV. But can bowtie be used for aligning single "reads" of a very large size to a chromosome?

Can anyone suggest a program or tool to create a chromosome map of specified genes given the target genome and DNA sequences of interest? Thank you!

You wouldn't need a bowtie alignment if you already have the genome coordinates from BLAST. Can you not just upload the genome coordinates of the genes you're interested in?

Have a look at genoverse (code on GitHub).

You can do what you want with both Spaln and GMAP. Both output GFF3 and SAM, so the results are easily viewed on IGV. Bowtie is not a good fit for this task indeed.

If you're making a web figure, this AngularJS directive might be useful.
