Yes, you can use SVG path as a shape for an element. What you chose really
depends on your objective. If you want to draw nodes (elements) and connect
them with edges (lines), I guess, the preferred API is Roassal2.

ah thank you very much, thats exactly what I was looking for. I will study
Trachel too. I also found that I can do something similar using a SVG path
with Roassal.

I think the intention of Roassal lines is to be connected with elements. If you
want only draw lines without any connection to elements, use directly Trachel.
I guess

well thats not an one liner and you still connect elements with it. I just
wanted to pass coordinates to a line and draw it. So I would prefer it if I
could pass points instead of elements.

yes i know about the example of a line connecting with other shapes. I
wanted just a simple line by itself starting from one point and ending to
another in a single line of code.

I have checked RTDirectedLine and it is not supposed to use the way you want.
Basically RTEdge is the object you want to manipulate with.
I do not know what is the objective of your example. But there is way how you
could write it.

to answer myself, view color changes via canvas so it is
v canvas color: Color black.
I also found a way to create an edge looking at the tests.
this is the complete code now
v := RTView new.
shape := RTEllipse new size: 20; color: Color red. shape := shape + RTLabel.
es := shape elementOn:'hel
Ok here comes the first question
how I change the background color of RTView ?
also
when I do this
v := RTView new.
shape := RTEllipse new size: 20; color: Color red. shape := shape + RTLabel.
es := shape elementOn:'hello'. v add: es.
line := RTDirectedLine new pointsFrom: 20@20 To: 30@30.
