Detect Graph Edges Overlapping

Error in mounted hook: "TypeError: edge is undefined" when using dagre-d3 with vue2

QUESTION

Detect Graph Edges Overlapping

Asked 2021-Feb-19 at 10:12

The problem: Looking for quite some time for a js graph library to create a directed graph (e.g. using dagre layout), with the constrain of non-overlapping edges.

Steps until now

Started with cytoscape.js but as it seems, such a feature doesn't exist.
Continued on with an svg based solution (considering that all elements are in the DOM), d3.js using the dagre-d3, but still the information in the DOM is the path route.

Objective

Find a way to detect edge overlapping, either canvas or svg based.
Create a custom layout to respect this constrain. Will use this as a metric for my convergence algorithm.

Graphical Representation

Below a graphical representation of the objective. I want to detect that edges 0>1 and 2>3 are overlapping.

Any ideas, thoughts are welcome. If there is something wrong with my logic, corrections/suggestions are more than welcome.

Finding edge crossings (line intersections) is a fairly simple bit of geometry which is explained here --> https://stackoverflow.com/a/18234609/368214

But then minimising such edge crossings in a graph (zero edge crossings are only possible in planar graphs) is one of the great research challenges of graph layout - https://cs.stackexchange.com/questions/14901/how-to-reduce-the-number-of-crossing-edges-in-a-diagram

Some graph layouts for specific graph types like DAGS such as Sugiyama aim to reduce crossings and similar cytoscape layouts are available at yfiles if that helps (i.e. the hierarchic layout) --> http://apps.cytoscape.org/apps/yfileslayoutalgorithms

QUESTION

Error in mounted hook: "TypeError: edge is undefined" when using dagre-d3 with vue2

Asked 2020-Oct-31 at 15:48

I'm trying to set up very simple example with Vue2 using dagre-d3 for rendering directed graphs. Unfortunately, even with extremely simple example, it wont work. Examples found elsewhere online are using older version of d3. Currently, Vue2 app is mostly default template with a router with a typescript as language. Diagram component is in javascript (due to missing types in my code for d3 and dagre-d3).

When running the component mentioned below, following error happens and nothing is shown in the block.
