Reliably get labels for Elastic Pie Chart

Question

I am trying to create a pie chart with elastic charts, and I'm having trouble trying to label the slices.

I'm following the example here. More specifically, for the layers prop:

layers={[
          {
            groupByRollup: (d: Datum) => d.sitc1,
            nodeLabel: (d: Datum) => productLookup[d].name,
          },
        ]}

The d in groupByRollup gives me the full entry for the data, but the d in nodeLabel only gives me the count for the data. There's no example for the productLookup object in the storybook.

I assume, oddly, I need to go back to my data object and find the label with the corresponding count. But what if I have a dataset where 2 entries have the same count? How do I reliably get the label?
