+<!-- prepare a DOM container with width and height -->
+<div id="main" style="width: 600px;height:400px;"></div>
+<script type="text/javascript">
+    // based on prepared DOM, initialize echarts instance
+    var myChart = echarts.init(document.getElementById('main'));
+
+    // specify chart configuration item and data
+    var option = {
+        title: {
+            text: 'ECharts entry example'
+        },
+        tooltip: {},
+        legend: {

+
+    // use configuration item and data specified to show chart
+    myChart.setOption(option);
+</script>
