How to plot a horizonal sugiyama graph

[seahurt]

I am tring to plot a horizontally placed graph, but got a little problem.

Below is the original graph from https://codepen.io/brinkbot/pen/oNQwNRv

After swipe the x and y by following code(change from line 144):

var { height, width } = layout(graph);

function TransNode(node){
  console.log("transform", node.data)
  let tmp = node.ux;
  node.ux = node.uy;
  node.uy = tmp;
}

function TransGraph(g){
  let tmp = width;
  width = height;
  height = tmp;

  for (let node of g.nodes()){
    TransNode(node);
  }
  for (let link of g.links()){
    let points = [];
    points.push([link.source.ux, link.source.uy]);
    points.push([link.target.ux, link.target.uy]);
    link.points = points;
  }
}

TransGraph(graph);

The result graph become this:

It seems like the path between nodes differed. But I don't known how to make it work. Could you please help me?

Or is there an option to plot horizontally placed graph directly?

you probably missed all of the x's and y's. Fortunately, this is now built in in the form of a tweak.

When constructing the layout function, there's a line in the example:

  .tweaks([shape]);

All you need to do is add another tweak to flip it:

  .tweaks([shape, d3dag.tweakFlip()]);

The edges will still look a bit weird due to the spline interpolation of d3. To fix that, change

const line = d3.line().curve(d3.curveMonotoneY);

to

const line = d3.line().curve(d3.curveMonotoneX);

You should then see:
