This is great, thanks!

@tadam50, just have 1 question. I see there is a horizontal example and vertical example. But can vertical and horizontal layouts be combined in 1 svg ?

For example we have 12 substations, then ideally we want to have 3 rows with each 4 substations...

@flieks Indeed, this would be a lot better! But this would be in another PR, this PR introduces a very basic version to start simple.

I'll write an issue for that feature, it would be nice if you could add some details about what you had in mind

@flo-dup @tadam50 Thanks for starting this PR, sorry for late reply
This is kind of what we are trying to achieve:

Dont mind the green and orange borders. This is to group substations. The green ones are substations.

I am trying to click on this one in the docs

but the page is not there yet. I guess it will come with this PR.

Because we need the vertical layout as you can see, our main substation busbars are vertical lines and then the connections that go to other substations are horizontal lines. It would be awesome if we could achieve something like this. Would this be possible with this PR or maybe another one ? Maybe we can help if you point us in the right direction of what should be changed/coded to get this working ?

i puted this info condensed in the other PR 520 also

Thank you for your nice work!
I didn't have time to finish my review, to be continued :)

Thank you for the huge amount of work you have put in this PR.
I made a minor comment, I would like to discuss it further with you because I do not get why there is a difference between substation and zone regarding layout naming (and furthermore I may be to blame here!).

Some configurations (VH and HV) do not offer a clear and completly satisfying display. But this PR is a first attempt to display multi-substation graphs. It will be followed by another PR to represent multi-substation graphs according to a matrix design.
