I am trying to get this donut charts with multiple ring working . This is using d3js v4. This is a continuation from another post where this was working in v3(multi-ring pie chart using d3js). The path created always shows up M0,0Z . Could anyone let me know where is this going wrong. I also get Expected lenght NaN in the console.

Pay attention that I extend data object with property parentIndex when I store the index of the current data item. In d3 version 3 you can get the index of parent data-item as third argument function(d,i,j) (j in this example), but in the d3 version 4, the third argument it's not the index.
var path = gs.selectAll("path")
.data(function(d, i) {
return pie(d.children).map(function(payload) { // <-- !!!
return {
payload: payload,
parentIndex: i
}
})
})
.enter().append("path")
.attr("fill", function(d, i) {
return color(i);
})
.attr("d", function(d, i) {
return arc
.innerRadius(10 + cwidth * d.parentIndex) //<-- !!!
.outerRadius(cwidth * (d.parentIndex + 1))(d.payload); //<-- !!!
