Add labels to edges

[blumonkey]

Not an issue, but an enhancement?

How can I add labels to the edges so that they are more descriptive in the relation between nodes? Can anyone please direct me in the right direction?

Thank You!

Did you ever figure out how to do this?
Thanks!

Any update?

I actually figured it out. Inside 'updateGraph' method, do:

const p = paths.enter().append("g");
//already given
    paths.enter()
      .append("path")
      .style('marker-end', 'url(#end-arrow)')
      .classed("link", true)
      .attr('id', d => {
        console.log(d.id);
        return "path" + d.id;
      })
      .attr("d", function (d) {
        return "M" + d.source.x + "," + d.source.y + "L" + d.target.x + "," + d.target.y;
      })
      .on("mousedown", function (d) {
        thisGraph.pathMouseDown.call(thisGraph, d3.select(this), d);
        }
      )
      .on("mouseup", function (d) {
        state.mouseDownLink = null;
      });
//start new code here
    p.append("text").attr("dy", -20)
      .append("textPath")
      .attr('id', d => {
        return ''+d.id;
      })
      
      .attr("text-anchor", "start")
      .style("font-size", 25)
      .style("fill", "#000")
      .style("text-anchor", "middle")
      .attr("startOffset", "50%")
      .attr("xlink:href", function(d) {
        console.log(d.id);
        return "#path" + d.id;
      })
      .text(function(d) {
        
        return d.func;
      });
