According to echarts4r::e_sunburst help page you can use either "json list hierarchical data representation" which seem to be simply a list or a "tibble hierarchical data representation".
The data.tree::ToListExplicit function seems to be able to transform Node objects from package data.tree into lists but it does not seem to work with echarts out of the box.
For example I would expect the following code to provide a graph :
library(data.tree)
library(echarts4r)
data(acme)
acme |>
ToListExplicit(unname = TRUE) |>
e_charts() |>
e_tree(initialTreeDepth = 3)
According the this discussion on github I would expect this to provide a graph :
acme |>
e_charts() |>
e_sunburst()
And with this approach I get only a partial graph with the first subnode :
jsonl <- acme |> ToListExplicit(unname = TRUE)
jsonl$children|>
e_charts() |>
e_tree(initialTreeDepth = 3)
