I'am trying to create circle-packing chart like that
https://bl.ocks.org/mbostock/4063530
But I also want to create some relation between data, to show how data binds to each other, so I need to add some code to change example above to make it like on this image: Circle chart with relational links
So the question is: is it possible to add relational between children in array to reach desired behavior and change Circle-chart layout to Linked Circle chart layout?
P.S. I'm new in d3.js so I don't have deep knowledge in this field, so It would be great if you provide me some examples how to reach that
