Is there any way to force graphviz to always draw the nodes above edges even if the edge is drawn over (or preferably under) the node?
So far I have tried ordering them and different layer options but not found a way that works.
You'll want to specify outputorder="edgesfirst". This can be found in the documentation.

In this force directed graph,
https://codesandbox.io/s/3d-force-graph-forked-le6ny7
I want all nodes in group 2 to repel each other alot, but I want all nodes with any other group combination to repel each other only a little.
I saw this answer for how to apply a custom force to only certain nodes.
https://stackoverflow.com/a/61985672
I added this in the codesandbox (for whatever reason, this code isnt applied on page load - it doesnt re-draw the graph until I make some kind of code change, like adding a newline. Weird).
But after re-drawing the graph, now the graph is in 2D - not 3D anymore.
How can I add a custom force to only certain nodes, AND keep the graph in 3D?
I used word to make this graph, how to make it in dot language? The line style is perpendicular. Thanks very much!
You can use the 'pos' attribute to place your nodes on an imaginary grid:
graph X
{
a [pos="1,1"]
b [pos="2,2"]
c [pos="2,3"]
d [pos="2,4"]
}
and then use the appropriate flag to the layout program to override neato's desire to place your nodes (you may also need to fiddle with the size of your nodes). You probably end up with edges which are not straight. In that case, define invisible nodes for the junction points on your imaginary grid and draw edges from your top node to the invisible ones and from the invisible ones to RIL_Init and so on. If your graphs are big, this will get pretty tedious..still straightforward...and you still get all the output options of graphviz. The need for pos="1,1!" usually comes up too, the bang meaning 'put it exactly there'.
I have a graph with a lot of objects. A number of these objects have no links. GraphVis lays these out on one long horizontal line on the top of the diagram.
Is there anyway to make GraphViz have a maximum width, so unconnected objects go on the next "line" ?
Add invisible edges between them. This will force graphviz to layout these nodes like the ordinary ones.
I would like to use graphviz for a project and am unable to get the behaviour I want. I have a graph that I can draw with graphviz just fine, but I also have a version of the same graph that has some extra edges. I would like the second graph to be drawn with the nodes in the same positions as the first one and the edges in the same positions, but the new edges to be drawn without avoiding any overlap with nodes.
To get a better idea of what I want, imagine a Powerpoint slide with a graph and then on the next slide the same graph with these extra edges that appear on top of the first graph, wihtout modifying the look of the old parts of the graph. That is the effect I want.
I think the effect could be achieved by having some edges ignore any overlapping constraints. I could not figure out how to control the overlap between edges and nodes for particular edges (or even for all edges).
Any ideas?
You can get dot to output another .dot file, with positions assigned to all elements, via dot -Tdot (or maybe dot -Txdot). Add your additional edges to that file, and run it through dot again to produce your second graph.
I'm trying to use GraphViz to draw graphical models. However, I didn't find a way to make draw overlapping clusters. For example, how can I make "nodeA->nodeB" to lie inside both clusterA and clusterB?
AFAIK you can't.
Clusters as described in the documentation:
If the name of the subgraph begins with cluster, Graphviz notes the
subgraph as a special cluster subgraph. If supported, the layout
engine will do the layout so that the nodes belonging to the cluster
are drawn together, with the entire drawing of the cluster contained
within a bounding rectangle.
The whole idea of clusters is not to overlap, but to group nodes (and graphviz raises an error when a node is part of two subgraphs).
