[Biopython] graphics library suggestions?

[Katie Edmonds]

It seems like even when I set the track height, the heights and the lengths
of the arrows (per base pair) are always changing depending on the lengths
of the sequences and the number of tracks in the figure. Is there any way
that I am missing to nail down these proportions?
