研究方向

Investigate how to retrieve AWS Lambda execution time and allocated memory from CloudWatch metrics. Consider using AWS SDK to fetch data and create a chart (e.g., using D3.js or a simple HTML canvas). The issue body shows three images with different memory settings, suggesting a need to plot cost (proportional to memory * time) vs execution time. Look at existing examples in the repository or AWS documentation. Since this is a learning repo, the result could be a new page or section in the README.
