sunburstR goes 2.0.0 with some new features
and bug fixes motivated by the feedback and discussion in issues 60 and
61.
I thought a vignette would be a good way to demonstrate.
Let’s get started by loading some packages and making some simple data to use throughout the post.
library(sunburstR)
packageVersion("sunburstR")
#> [1] '2.1.8'Simple data should suffice for these examples.
library(htmltools)
#> Warning: package 'htmltools' was built under R version 4.1.3
library(d3r)
dat <- data.frame(
level1 = rep(c("a", "b"), each=3),
level2 = paste0(rep(c("a", "b"), each=3), 1:3),
size = c(10,5,2,3,8,6),
stringsAsFactors = FALSE
)
knitr::kable(dat)| level1 | level2 | size |
|---|---|---|
| a | a1 | 10 |
| a | a2 | 5 |
| a | a3 | 2 |
| b | b1 | 3 |
| b | b2 | 8 |
| b | b3 | 6 |
d3r
will help us build our hierarchy.
library(d3r)
tree <- d3_nest(dat, value_cols = "size")
tree
#> {"children":[{"name":"a","children":[{"name":"a1","size":10,"colname":"level2"},{"name":"a2","size":5,"colname":"level2"},{"name":"a3","size":2,"colname":"level2"}],"colname":"level1"},{"name":"b","children":[{"name":"b1","size":3,"colname":"level2"},{"name":"b2","size":8,"colname":"level2"},{"name":"b3","size":6,"colname":"level2"}],"colname":"level1"}],"name":"root"}legend = FALSE
Often the legend in the sunburst becomes useless with lots of nodes
and multiple levels. While a hack could turn it off, I don’t like having
to ask users to resort to hacks, so now the argument
legend = FALSE will turn it off.
sb1 <- sunburst(tree, width="100%", height=400)
sb2 <- sunburst(
tree,
legend = FALSE,
width = "100%",
height = 400
)
# do side-by-side for comparison
div(
style="display: flex; align-items:center;",
div(style="width:50%; border:1px solid #ccc;", sb1),
div(style="width:50%; border:1px solid #ccc;", sb2)
)d2b Sunburst
Kevin Warne has built an incredible sunburst in d2b, so
I just had to add it to sunburstR. I think Kevin’s work
definitely deserves a star on Github, and with only 32, I
encourage a quick detour to share the love.
I love treemap, and I enjoy using the results from
treemap in a sunburst. However, recent changes resulted in
double-counted sums as discussed in this issue.
This double counting happens when the tree is pre-summed. I added a
sumNodes = FALSE argument to disable the auto-sum.
This is hard to see, but I discovered that the breadcrumbs were duplicated on each resize. This commit shows the bug fix if anyone is interested.
