In this example [Plot: Horizontal bar chart with a label / Observable | Observable](https://observablehq.com/@observablehq/plot-horizontal-bar-chart-with-label?intent=fork) I would like to add data attribute, not areaLabel/ariaDescription, to the text with the words “Apple”, Google", etc. How can I do this?

Help please

Data attributes are not natively supported at the moment (maybe it could be added as a feature request). It’s probably _possible_ to add them (if a bit difficult) using a [render transform](https://github.com/observablehq/plot/pull/1811) and custom channels.
