A zoomable, pannable hierarchical bubble chart HTML Widget for R implemented in d3v4.
This is work in progress, but you can find a working example of a Shiny app within the repo.
The widget expects data in the following format (showing first few rows only):
| id | parent | text | value |
|---|---|---|---|
| 1 | NA | Total | 8804.544 |
| 2 | 1 | category a | 8804.544 |
| 3 | 2 | category d | 8804.544 |
| 4 | 3 | category g | 5921.133 |
| 5 | 4 | category k | 5921.133 |
| 6 | 3 | category i | 2883.411 |
| 7 | 6 | category l | 2883.411 |
However, you're more likely to have data that looks like this (first few rows only):
| cat_1 | cat_2 | cat_3 | cat_4 | val |
|---|---|---|---|---|
| category c | category e | category g | category k | 6760.6001 |
| category b | category e | category g | category j | 4690.3694 |
| category a | category f | category i | category j | 445.0382 |
So a convenience function is provided that converts between the two:
df <- hierarchicalbubble::generate_test_data()[1:5,]
names <- paste0("cat_", 1:4)
df_l <- hierarchicalbubble::wide_to_long_hierarchy(df,names, "val")
To see your visualisation use
hierarchicalbubble::hierarchical_bubble(df_l)
