From time to time, I see some beautiful racing chart pages online, showing how data changes over time, which looks really cool. After researching, I found that there are ready-made JS libraries that can generate such charts, but I couldn't find a suitable tool that could automatically generate racing charts after uploading data.

So I thought about implementing one using Claude3.5, but the process wasn't smooth, and I encountered quite a few pitfalls along the way. I started working on it in July, trying intermittently multiple times, until recently when I finally managed to implement a simple version. This article records the process of implementing this tool using Claude3.5 and documents the pitfalls encountered along the way. You can experience the final result here, and feel free to leave comments for discussion.
