好的,这是一个数据可视化的问题。您需要使用Python中的pandas和matplotlib库来完成这个任务。以下是代码实现的步骤:
1. 导入所需的库
```python
import pandas as pd
import matplotlib.pyplot as plt
```
2. 读取数据文件vgsales.csv
```python
data=pd.read_csv('vgsales.csv')
```
3. 统计平台数量并排序,只保留数量排名前5的平台
```python
platform_count=data['Platform'].value_counts().sort_values(ascending=False)[:5]
```
4. 绘制饼图,展示各平台游戏软件数量分布情况
```python
plt.pie(platform_count,labels=platform_count.index,autopct='%1.1f%%')
plt.title('Top 5 Platforms for Video Games')
plt.show()
```
完整代码如下:
```python
import pandas as pd
import matplotlib.pyplot as plt
data=pd.read_csv('vgsales.csv')
platform_count=data['Platform'].value_counts().sort_values(ascending=False)[:5]
plt.pie(platform_count,labels=platform_count.index,autopct='%1.1f%%')
plt.title('Top 5 Platforms for Video Games')
plt.show()
```
运行代码后,会显示一个饼图,展示了数量排名前5的平台游戏软件数量分布情况。
