Hi Folks

I often thought it would be nice to be able to produce a graph of the
visibility windows for satellites for a geographical location, but have not
seen any software package that produce such an output. 

After seeing the graphs in
I thought it would be even better to have a graph per satellite with time
(date) along the x-axis and altitude along the y-axis. 

Is anyone aware of software that produce something like this?
