how write line between circle in center , each of outer circles?

i tried canvas , getting center coordinates via offset , easy math, canvas wouldn't or can't that.

i'd appreciate guys.

cheers!

taking mind not want use canvas (or not feasible) made ​​a solution using css3 transform ...

follows solution

in jsfiddle -> http://jsfiddle.net/d6pyr/2/

you need create more 1 css class make line 

.line {      border-top: 1px solid black;      position: absolute;      height: 1px;      opacity: 0;      -webkit-transform-origin: left;      transform-origin: left; }

to create element can create in loop

    var line = $("<div class='line'></div>");     slider.append(line);     line.css("width", 0);              line.css("top", center_top + ( $(this).height() / 2 ) );     line.css("left", center_left + ( $(this).width() / 2 ) );     line.css("transform", "rotatez(" + angle + "rad)");
