in thread How to draw a curved arrow in perl Tk canvas ?

would also require to draw a self loop for a node in a canvas,i.e, an edge that will start and end in the same node showing a small loop.

Isn't that simply a circle? See Tk::Canvas createOval().

    Not actually...I wanted using the createLine....but indeed it was simple..I figured it out just after posting :)
    my ($x1,$y1); my $r = 50; # radius my @new_coords = ($x1,$x2,$x1-$r,$x2+$r,$x1,$x2+(2*$r),$x1+$r,$x2+$r,$ +x1,$x2+8); $id = $can->createLine(@new_coords);
    Thanks for the help anyways...
