Plot poly-lines between few points in D3+Polymaps

Question

I would like to create polyline on the click of the mouse. I have 4 circles 3 with radius 2 (Lets name it as B,C,D) and 1 with radius 8 (Lets name it as A). Now when I click on the circle A, poly line should be made which connects A to B, A to C & A to D.

I have the lat and long of A,B,C,D. Also the polyline from Circle A to B,C,D should be of different width and maybe color.

I have looked into the following suggestions

1. Polymaps + D3+ Polyline with different width and color (This one is asked by me but could not get the right output, my apologies for duplication, since I really need to get an answer for this ASAP )

2. how we create line between two cordinates on polymap?

3. http://webcache.googleusercontent.com/search?q=cache:vVkS6oWCxnsJ:groups.google.com/group/d3-js/browse_thread/thread/ccd1c8a4f8b85855+&cd=3&hl=en&ct=clnk&gl=in

But could not get much help, I would appreciate if you can give me some advise or code anything to start in the right direction

Thanks

Mehul

As suggested by your post I have made this js but does not seem to work was wondering if you can have a look at it and let me know the mistake

{// JavaScript Document

 var po = org.polymaps;
 var svg = n$("#map").add("svg:svg");
 var map = po.map()
.container($n(svg))
.center({lat: 33.787, lon: -118.195})
.zoom(9)
.add(po.interact());
 map.add(po.image()
.url(po.url("http://{S}tile.cloudmade.com"
+ "/1a1b06b230af4efdbb989ea99e9841af" // http://cloudmade.com/register
+ "/998/256/{Z}/{X}/{Y}.png")
.hosts(["a.", "b.", "c.", ""])));
 map.add(po.compass()
.pan("none"));

//map.add(po.geoJson()
var map = po.map();
var layer = po.geoJson();
var featAtoB ={ "type": "Feature",
"geometry": {"type": "Point", "coordinates": [[-118.195, 33.768],[-117.914, 33.768]]},
  "properties": {"prop0": "value0"}
  },
{ "type": "Feature",
  "geometry": {
   "type": "LineString",
   "coordinates": [
      [-118.195, 33.768],[-117.914, 33.768]
     ]
   },

   "properties": {
     "prop0": "value0",
     "prop1": {"this": "that"}
     }      
  };
 layer.features([featAtoB]);

map.add(layer);
