@evaristoc I think you should explore the modules and become a D3 superfan so you can take over my title of "D3 queen" so I can focus on other stuff that I don't hate doing because they're not in JavaScript ;)

@becausealice2 I will do my best. However I don't think the D3 queen title will suit my preferences... I am happy with D3 master.

@GoldbergData sorry you found it long. Probably one that interest more to people working on advanced topics in neural nets.

Maybe many of you are not interested but I need to correct:
"Symplectic" is NOT those where "the inner product is defined" as I suggested above: it is a definition of a complex space "equiped with a simplectic bilinear form (wikipedia, symplectic vector space)" (here the notion of the inner product). The existence of the inner product as part of the space is more a definition of the Banach space, which are those completed normed. However, Banach spaces can be normed in different ways. When the norm is uniquely based on the inner product, the it is called Hilbert space. So I also made a mistake here too.

It seems to be that the relation is:

symplectic space ⊂ hilbert space ⊂ banach space

Sorry. Again, not a mathematician... just like it.

It seems that the numerical method to solve the velocity Verlet of the d3.js force layout simulation is mainly based on a solution that transform into a complex space. If I am not wrong, numerical Poisson solvers are of that kind, eg. Fourier Transforms.
Fiuuu!! That was a awful revision. Sorry if that doesn't work for you. It might not for me either. Again, this is just fun.

@evaristoc I think it’s very interesting. I just wasn’t able to read it on in my current setting. No need to apologize. Thanks for sharing.
