Stacking 3D Cubes with Spacing

This is to give you a start. I essentially recycled and slightly modified the code from this answer. With these definition, drawing the vector is as simple as

\path pic{cube array={num cubes x=3}};

MWE:

You can adjust the view at will.

Run it with pdflatex --shell-escape <file>:
