# 读取CSV文件
data = pd.read_csv('shipping_data.csv')

# 提取年份和运输量
years = data['Year']
shipment_volumes = data['Shipment_Volution']

# 创建条形图
plt.figure(figsize=(10, 6))
plt.bar(years, shipment_volumes, color='blue')

# 添加标题和轴标签
plt.title('海运运输量随年份的变化')
plt.xlabel('年份')
plt.ylabel('运输量')

# 显示图形
plt.show()
