D3.js Chord Diagram - Make chords touch the pulled apart arc

D3 and Javascript newbie here. I am making a chord diagram with one arc that is pulled apart from the center. I have managed to move the arc into my desire position but I wonder how do I make the group of chord touching the arc again and not messing up the position of other groups of chords?



Here is an image to explain my desired result.





I am currently using an if statement to select the angle where arc C is staying and translate its position.



.attr("transform", function(d) {

            if (d.startAngle > Math.PI*1/2 && d.startAngle < Math.PI*5/6) {

                            return "transform", "translate(" + pullOutSize + "," + pullOutSize + ")"}

        ;})


I am able to translate the position of the chords by using the translate as well. 



.attr("transform", "translate(" + 50 + "," + 50 + ")")

.attr("d", path);




However, when I applied the same if statement to it the translate stop working. It seems like the if statement does not met the condition. I wonder what will be the right statement to put into the if statement to help me select the section of chords that I am trying to move.



.attr("transform", function(d) {

            if (d.startAngle > Math.PI*1/2 && d.startAngle < Math.PI*5/6) {

                            return "transform", "translate(" + pullOutSize + "," + pullOutSize + ")"}

        ;})


Thanks!

According to the documentation, you can pass the radius as a parameter when creating the chord/ribbon.



Documentation for ribbon



// from documentation

   var ribbon = d3.ribbon();

     ribbon({

            source: {startAngle: 0.7524114, endAngle: 1.1212972, radius: 240},

            target: {startAngle: 1.8617078, endAngle: 1.9842927, radius: 240}

     });

      According to the documentation, you can pass the radius as a parameter when creating the chord/ribbon.

        According to the documentation, you can pass the radius as a parameter when creating the chord/ribbon.



        Documentation for ribbon



        // from documentation
        
   var ribbon = d3.ribbon();
        
     ribbon({
        
            source: {startAngle: 0.7524114, endAngle: 1.1212972, radius: 240},
        
            target: {startAngle: 1.8617078, endAngle: 1.9842927, radius: 240}
        
     });

            Full-time equivalent From Wikipedia, the free encyclopedia Jump to navigation Jump to search Full-time equivalent ( FTE ) or whole time equivalent ( WTE ) is a unit that indicates the workload of an employed person (or student) in a way that makes workloads or class loads comparable [1] across various contexts. FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load. [2] Contents 1 U.S. Federal Government 2 In education 2.1 Example 3 Notes 4 References U.S. Federal Government [ edit ] In the U.S. Federal Government, FTE is defined by the Government Accountability Office (GAO) as the number of total hours worked divided by the maximum number of compensable hours in a full-time schedule as
