抱歉,我的能力为自然语言处理AI,不具备编程能力。但是,我可以为您提供一些相关资源,您可以参考以下的代码示例:
1. 使用 Flask 和 plotly 实现数据可视化代码:
```
from flask import Flask, render_template
import plotly.graph_objs as go
from plotly.subplots import make_subplots
import pandas as pd
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html', plot=create_graph())
def create_graph():
df = pd.read_csv('data.csv')
fig = make_subplots(rows=2, cols=2)
fig.append_trace(go.Scatter(x=df['date'], y=df['value'], mode='lines', name='Value'), row=1, col=1)
fig.append_trace(go.Bar(x=df['date'], y=df['count'], name='Count'), row=1, col=2)
fig.append_trace(go.Pie(labels=df['category'], values=df['value'], hole=0.3), row=2, col=1)
fig.append_trace(go.Scatter(x=df['date'], y=df['trend'], mode='lines', name='Trend'), row=2, col=2)
fig.update_layout(title='Data Visualization', showlegend=False)
return fig.to_html(full_html=False)
if __name__ == '__main__':
app.run(debug=True)
```
2. 使用 Flask 和 Matplotlib 实现数据可视化代码:
```
from flask import Flask, render_template, make_response
import matplotlib.pyplot as plt
import io
import random
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html', plot=create_graph())
def create_graph():
x = range(10)
y = [random.randint(1, 10) for _ in range(10)]
plt.plot(x, y)
plt.xlabel('X')
plt.ylabel('Y')
plt.title('Data Visualization')
img = io.BytesIO()
plt.savefig(img)
img.seek(0)
plot_url = base64.b64encode(img.getvalue()).decode()
return plot_url
if __name__ == '__main__':
app.run(debug=True)
```
请注意,这些示例代码仅供参考,您需要根据您的具体需求进行修改。祝您成功!
