Line,Plane, Points 3D, Intersection,

Is there a tutorial on -analytical geometry(vectors) : plane line 2D circle in 3D, plot chains of vectors, basicaly the everything what this thing can do: https://www.geogebra.org/3d?lang=de well allmost everything in vector geometry for python or sagemath.

Maybe someone saw a book or tutorial on this

I can not find anything on this.

I have managed to plot points

from sage.plot.plot3d.shapes2 import frame3d 
F=frame3d([0,0,0],vector([10,10,10]),color='red')
A=point3d((4,3,2),size=10,color='red',opacity=.5)
e=0.2
eps=vector([4+e,3+e,2+e])
T = text3d('A',eps)
F+A+T

I didnt manage to label, point A(4,3,2), to to do it? I would rather not put the coordinates as a string. Is there something like in c++ "The point is %d"

Is there a better way to plot? I need the frame, since the plot 3d is not accepting, text, or maybe i am wrong?

Would there by a natural way to plot x,y,z axes?

Here is the Code https://share.cocalc.com/share/a3f14e05-7729-406f-97c5-be5b73646381/vector/ebene.sagews?viewer=share
