It is unclear on https://github.com/codeplaysoftware/syclacademy/blob/main/Lesson_Materials/common-revealjs/images/ndrange-example-work-item.png and https://github.com/codeplaysoftware/syclacademy/blob/main/Lesson_Materials/common-revealjs/images/ndrange-example.png how to infer which dimension is, where each axis is growing, etc. A good start would be to avoid square configuration. All these...

There is almost no example in the slides of 2D and 3D `range`, `buffer`, `accessor`, `id`... and there were a lot of questions at CppCon 2021 about it.
