Visualizing non-business data

I am a novice at visualization.  I am trying to create a visualization with non-business data that shows start and stops in a linear fashion.

I am using genome data that contains start/stop coordinates.  Each patient has multiple start/stops per chromosome.  I would like to show for each patient all the start and stops along a straight line/column/bar.

Example data:

Patient = 12

Chromo = chrX

Start = 10     Stop = 15

Start = 24     Stop = 32

Start = 45     Stop = 47

And so on...

Anybody got an ideas?

Thanks so much
