导读：html：其实就是根据table标签把几个实心圆div进行等边六角形的排布，并放入一个div容器中，然后利用CSS3的循环旋转的动画效果对最外层的div容器进行自转实现，当然不要忘了把div容器的外边框设置圆形弧度的。

css：因为在圆形的轨迹中有6个实心圆，分别设置了不同的类以方便自定义，所以当中实心圆的样式设置有重复的地方，还可以进行优化，在这就先不处理了

      }

      .isSelected {

          border: 1px solid red;

      }

  </style>

JS：这里的代码可以不实现，因为这跟动画的效果无关，是一个点击的响应事件

angular.module('starter.controllers', [])

    .controller('healthCtrl', function($scope, $location) {

        $scope.clickUrlKey = "BMI";

        $scope.compriseClicked = function(clickUrlKey) {

            $scope.clickUrlKey = clickUrlKey;

        };

    })
