Find the best Algo and options for my graph [message #1782184]

Hi,

I need help to find best options and layout algorithm for my case .
I have a graph like this :

index.php/fa/32138/0/

I get this bad result with force layout algorithm.

and i want to get a result like this to reduce edge cross and overlap :

index.php/fa/32139/0/

could you help me for this ?

Regards

Our layout algorithms won't give you the exact kind of result as in your example. Perhaps you could give us a little more context as to what these diagrams actually represent so we can find an alternative layout that our algorithms can supply?

i know that algorithms won't give exact result but i don't undestrand why edges length are not "optimal"

ex : why "1099" node circle is in top of "Java" node and not between "Java" and "plae-dl1" node?

relations are like this :

plae-dl1 --> "1099" --> java
and
plae-dl1 --> java

One of the main problems in your graph are edges that transcend hierarchy boundaries. That is, an edge incident to one of the circles is not necessarily connected to one of the circle's siblings, but instead to nodes contained in one of the siblings. ELK Layered can in fact handle that case if you activate [i]hierarchy mode[i]: simply set the layout option LayeredOptions.HIERARCHY_HANDLING to HierarchyHandling.INCLUDE_CHILDREN on the outermost node.
