d3 hierarchy as R nested tibble

After Jenny Bryan’s fantastic PlotCon presentation Data Rectangling, I started thinking what would a d3.js hierarchy look like as a nested tibble.

d3r Shows Us

I had forgotten that in d3r::d3_nest I provided an argument to get the tibble instead of the JSON, so getting an example on your machine should be fairly simple (let me know if it isn’t). We will use the helpful random.hierarchical.data function in the treemap package to generate the data.

# install.packages("d3r")
# install.packages("treemap")
library(treemap)
library(d3r)

d3_nest(
  random.hierarchical.data(),
  json = FALSE
)[,c("id","children")]
## # A tibble: 1 × 2
##      id         children
##   <chr>           <list>
## 1  root <tibble [4 × 2]>

Still No Easier to Query

Unfortunately, even though we can get the data in this form, I don’t think R tooling makes it any easier to query or manipulate. Please let me know if you have ideas or a workflow for working with this type data in R. data.tree seems to be our best option.
