<div id="main" style="width: 600px;height:400px;"></div>
<script type="text/javascript">
var myChart = echarts.init(document.getElementById('main'));
var option = {
"title": {
"text": 'ECharts 入门示例'
},

"data": ['销量']
},
"xAxis": {
"data": ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
},
"yAxis": {},
"series": [

"name": '销量',
"type": 'bar',
"data": [5, 20, 36, 10, 10, 20]
}
]
};
myChart.setOption(option);

from flask import Flask, render_template
app = Flask(__name__)
@app.route("/")
def home():
return render_template("helloEcharts.html")
if __name__ == '__main__':
#app.run(debug = True)
app.run(host='127.0.0.1', port=5000, debug=True)
