well, if you want to do it "right" one approach is the following,
generate the bresenham points on the line, use them as centers
for drawing properly filtered disks (circles) at each point.

depending on the filter you can have a variety of line types, from a 
soft, felt-tipped pen look, to a hard edged thing...

we here at pixar are big fans of properly filtering things...
