                margin: 0;
            }
        </style>
        <div id="main">
        </div>
        <script>
            var chart = echarts.init(document.getElementById('main'));
            var option = {
                tooltip: {},
                series: [ {
                    type: 'wordCloud',
                    gridSize: 2,

                        normal: {
                            color: function () {

                                    Math.round(Math.random() * 160)
                                ].join(',') + ')';
                            }
                        },
                        emphasis: {
                            shadowBlur: 10,
                            shadowColor: '#333'
                        }
                    },
                    data: data
                } ]
            };

            chart.setOption(option);

            window.onresize = chart.resize;
        </script>
    </body>
</html>

报错信息为，应该是 echarts 的 utils 为空值导致。

期望：能得以解决，或找出问题原因。
