Re: Proportional line width, precise anchor points

My guess is that it was probably done by an intern... manually,  
tediously, but cheaply.  ;-)

Moving the magnets will work, but they seem to move somewhat  
granularly.  I usually resort to setting "disable connections" on some  
lines, so that I can position their points more precisely.

One advantage of OmniGraffle is that you can set transparency for line  
colors... it would really help when lines cross over each other.


Political note: That graph is scary.  It looks like insulating my home  
is the least important thing to do!  More energy is used/lost  
everywhere else.
