Hi!

I am trying out to use d3.stratify() on a csv.  
where the CSV has 2 columns: Parent, Name

var csvData = d3.csv({CSVURL})  
var stratify = d3.stratify().id(d =\> d.Name).parentId(d =\> d.Parent)  
var hierarchyData = stratify(csvData) // Here is where I got “Error: missing: Dashboard”

Hope that someone can advise me on this.

Thanks!

I managed to solve my problem.

1. For hierarchyData, there can only be 1 null Parent with a Main Child
2. Main Child can be the Parent for many Children for illustration.
