Can Link Type or Trees to have a cycle ?

[Jasminou]

Hi,

I wanted to know when using a Link Type or Trees

is it possible to have a cycle within the Tree/graphe ?

example:

{
          name: "C",
          children: [
            {
              name: "C1"
            },
            {
              name: "D",
              children: [
                {
                  name: "D1"
                }
              ]
            }
          ]
 }

can C1 and D node be linked to the same D1 Node ?

Hey @Jasminou 👋 thanks for checking out visx. The @visx/hierarchy package largely depends on d3-hierarchy, and all of the hierarchical layouts available in d3 require a hierarchy structure where every node has a single parent.

I think what you're describing is more of a true network, not a tree/hierarchy. So @visx/network would likely be what you need ... however we haven't ported over any of the d3 network layouts (which are harder to get right in react) so it may not be useful for that case.

Thank you @williaster
so with the network package I will need to manage the layout right and the position of the node

yep that's correct, so it's much more work than the Trees/Links unfortunately. You could use d3 packages for the math for the layout, and then still render in react.
