Complex d3.nest() manipulation

Question

I have an array of arrays that looks like this:

var arrays = [[1,2,3,4,5],
              [1,2,6,4,5],
              [1,3,6,4,5],
              [1,2,3,6,5],
          


        

Answer 1

Edit - fixed

Here is my solution Pro:It is all in one go (doesn't need objects converting to arrays like above) Pro:It keeps the size/value count Pro:the output is EXACTLY the same as a d3 flare with children Con:it is uglier, and likely less efficient Big Thanks to previous comments for helping me work it out.

    var data = [[1,2,3,4,5],
        [1,2,6,4,5],
        [1,3,6,4,5],
        [1,2,3,6,5],
        [1,7,5],
        [1,7,3,5]]

    var root = {"name":"flare", "children":[]} // the output
    var node // pointer thingy
    var row



// loop through array
for(var i=0;i

Output

{ "name": "flare", "children": [ { "name": 1, "children": [ { "name": 2, "children": [ { "name": 3, "children": [ { "name": 4, "children": [ { "name": 5, "size": 1 } ] } ] }, { "name": 6, "children": [ { "name": 4, "children": [ { "name": 5, "size": 1 } ] } ] } ] }, { "name": 3, "children": [ { "name": 6, "children": [ { "name": 4, "children": [ { "name": 5, "size": 1 } ] } ] }, { "name": 3, "children": [ { "name": 6, "children": [ { "name": 5, "size": 1 } ] } ] } ] }, { "name": 7, "children": [ { "name": 5, "size": 1 }, { "name": 3, "children": [ { "name": 5, "size": 1 } ] } ] } ] } ] }
