Code看世界 用数据解读复杂的世界

import pandas as pd
import plotly.express as px

# 加载军费数据
df = pd.read_csv('military_spending.csv')

# 数据清洗
df = df.dropna()
df['year'] = pd.to_datetime(df['year'])

# 可视化
fig = px.line(df, x='year', y='spending',
              color='country',
              title='全球军费支出趋势')
fig.show()
