Python 语言 开发疫情数据可视化仪表盘 Plotly+Flask

Python疫情数据可视化仪表盘开发：Plotly+Flask实践指南

随着全球疫情的持续发展，对疫情数据的实时监控和分析变得尤为重要。Python作为一种功能强大的编程语言，在数据处理、分析和可视化方面有着广泛的应用。本文将结合Plotly和Flask，展示如何开发一个疫情数据可视化仪表盘，帮助用户实时了解疫情动态。

准备工作

在开始之前，请确保您的Python环境中已安装以下库：

- Flask：用于创建Web应用
- Plotly：用于数据可视化
- Pandas：用于数据处理
- Matplotlib：用于数据可视化（可选，Plotly已包含大部分Matplotlib功能）

安装方法如下：

bash
pip install flask plotly pandas matplotlib


数据准备

我们需要获取疫情数据。这里以中国疫情数据为例，数据来源于国家卫生健康委员会。

```python
import pandas as pd
