Network graph - Algorithm about highcharts

[karolkolodziej]

Hi @kogratte!

Thank you for the feedback. Technically you can adjust the layout algorithm via options.

I would like to be able to pick a layout algorithm from anywhere, and use it to place nodes.

I'm not sure how this should work, could you please elaborate?

Hey @karolkolodziej , thanks for coming back to me on this topic!

I'm having issues with the rendering algorithm, when working with complex networks (cf joined image).

This output is impacted by another issue I opened, which is I cannot move a single node without another one being moved as well (magic...), but this is not what I'm trying to point right now.

As you may have seen in the attachment, our "graph" is quiet complex, as it involves those kind of items:

• Providers
• Regions
• Routers
• Clients / Apps

Each level has a 1-n relation with the following one, and routers have a n-n relation to other routers (each router having at least one relation). They cannot be orphan nodes in our tree (that's important).

I tried a lot of combination with layout options, but I've never been able to get a decent layout, without proper positioning according nodes weight.

For example, let's take a look at the excellent vis-network library. https://visjs.github.io/vis-network/examples/network/basic_usage/standalone.html

Their modules can be used as standalone, due to a "recent" refactorisation.

The point here is to be able to pick their algorithm, or any other one picked on the internet, and use it to generate node positions.

For the time being, we can use "random", "circle", or provide a function which returns [x, y].

But those are only initial positions..

Thank you for the explanation!
For now, only one type of algorithm is available but it is a good idea to extend it or give the ability for users to implement their own.
