尊敬的开发者:
您好！
我想实现youtube的先进案例，我该如何做？具体是https://www.youtube.com/watch?v=WkkbrgP7Sss&t=1780s中的第一个案例演示
请按照 YouTube 视频中的说明进行操作，如果遇到任何具体问题，请告诉我们。由于维护者都不懂中文，如果您用英语发布问题，我们会更容易提供帮助。（如果有任何错误，还请见谅，此回复由 ChatGPT 翻译。）
Dear developers:
Due to my carelessness, I did not help you understand the meaning. I want to visualize the developer’s case on the YouTube video mentioned above, but I couldn’t find the corresponding case and tutorial. What should I do next? Thank you for your reply and assistance.
Unfortunately the notebooks for this example are not available
