I'm pretty sure the author spent more time writing and tweaking their prompt than it would've taken them to simply draw the graph they wanted. This isn't merely a matter of illustrating prompt engineering in humans vs machines.
I get the point the author is trying to make, but I really wish the example felt less contrived.
The actual timeline is reversed; I started with the sketch, submitted it to fiverr, realized I wanted to make a comparison to dalle, and only then I tried to come up with a prompt that could encapsulate the whole image.
I can see how it felt contrived, but I hoped to make an apples-to-apples comparison on a real use case. Then to reduce the complexity I tried it on a much simpler prompt.
