Use svg with angularjs ng-repeat

Question

I am learning angularjs and I am trying use ng-repeat to create an svg graph.

I have this html:

<svg>
    <g id="g_{{$index}}" ng-repeat="i in range" ng-cloak>
        <rect x="{{i / 5}}" y="{{i / 5}}" width="{{i / 5}}" height="{{i / 5}}"></rect>
    </g>
</svg>

the 'range' is just a simple array which is defined in controller like this:

$scope.range = [100, 200, 300];

the html is working; the rects are rendered on my page.

However, Chrome keeps throwing the following error:

Error: Invalid value for <rect> attribute height="{{i / 5}}"    js/angular.js:1584
  JQLiteClone   js/angular.js:1584
  JQLite.(anonymous function)   js/angular.js:2163

  self.fireWith js/jquery-2.0.0.js:2975
  jQuery.extend.ready   js/jquery-2.0.0.js:398
  completed js/jquery-2.0.0.js:93

It seems that it does not quite like what I am doing...

Does anyone have an idea why I'm receiving this error?

Markus' comment to use late binding is best.

Ie. prefix your attribute with either 'ng-attr-', 'ng:attr:' or 'ng_attr_', like this:

<rect ng:attr:x="{{i / 5}}" ng:attr:y="{{i / 5}}" ng:attr:width="{{i / 5}}" nng:attr:height="{{i / 5}}"></rect>
