在Python中创建数据可视化网页通常需要结合前端技术(如HTML、CSS和JavaScript)以及后端服务(比如Flask或Django)。以下是一个简单的例子,展示如何使用 Flask 框架和 Plotly 进行数据可视化,并将其嵌入到 HTML 页面:
首先安装所需的库:
```bash
pip install flask plotly dash dash_core_components dash_html_components
```
然后,创建一个名为 `app.py` 的文件,编写以下代码:
```python
from flask import Flask, render_template
import plotly.express as px
# 假设我们有一个数据集
data = px.data.gapminder().head(10)
app = Flask(__name__)
@app.route('/')
def index():
fig = px.line(data, x='year', y='lifeExp', color='continent')
return render_template('index.html', figure=fig.to_json())
if __name__ == '__main__':
app.run(debug=True)
```
接下来,在项目根目录下创建一个名为 `templates` 的文件夹,并在其中创建一个 `index.html` 文件:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Data Visualization</title>
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
</head>
<body>
<div id="chart"></div>
<script>
const json_figure = {{figure}};
const div = document.getElementById('chart');
Plotly.newPlot(div, json_figure);
</script>
</body>
</html>
```
这个简单的应用启动一个本地服务器,当你访问 http://localhost:5000/ 时,你会看到一个包含动态线图的页面。
