ND-range images are too symmetric

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 images should be somewhere in a vector format (SVG?) so they can be edited.

I think originally we used draw.io and I thought the files for editing were there but looks like they are not. Will investigate that.
