The Group command is as part of a structure passed to NewCanvas in order to create a group collection when creating a canvas.

$\mathrm{cv}≔\mathrm{NewCanvas}\left(\left[\left[\mathrm{Group}\left(\left[\mathrm{Math}\left(x^2\,\mathrm{annotation}=''Group\; 1''\right)\,x^3\right]\right)\,\mathrm{Group}\left(\left[\mathrm{Math}\left(y^2\,\mathrm{annotation}=''Group\; 2''\right)\,y^3\right]\right)\right]\right]\right)\:$

$\mathrm{ShowCanvas}\left(\mathrm{cv}\right)$
