What I typically do is something like:
x=evt.clientX;
y=evt.clientY;
L1.setAttribute("x1",x);
L1.setAttribute("y1",y)
L1 is a line
where this is done onmousemove.
this moves just one endpoint of the line as the mouse moves. What can
get tricky is the assignment and subsequent withdrawal of
event-handlers to things.
Take a look at the polyline tool in
http://srufaculty.sru.edu/david.dailey/svg/polylineBest.html (IE only
at the moment) for an application.
