I have constructed hierarchies following simple steps of importing the data, parsing it, stratifying it. The [Tidy Tree](https://observablehq.com/@observablehq/plot-tree-tidy) works well, but when this is included, the labels do not show:

const root = d3.hierarchy(data);

On a related note, what does “Qd” mean at the beginning of a cell for hierarchical data? I notice in Mike Bostock’s Tidy Tree example, the data is simply an array. After stratification, the data comes out already set up in a hierarchy (clearly). Is the const root = d3.hierarchy(data); messing this up?

I’d appreciate insight to this.

`Qd` is the name given to the `Node` object once the code is minified. See [d3.hierarchy / D3 | Observable](https://observablehq.com/@d3/d3-hierarchy) for an introduction to this module
