GLMakie: Point2f not defined

[Freya_the_Goddess]

This one works,

I try

pkg> activate --temp
pkg> add <packagename>
julia> include<"glmakie2.jl">

to start a new environment and it still can’t work with the GLMakie, not opening the Makie GUI.

using yours:

works amazingly. Thanks for the knowledge and help. Wish you all the best.
