FAQ
Sunburst Chart Maker questions
- How do I structure hierarchical data?
- One column per level, ordered from the outermost grouping to the innermost, then a numeric value in the last column. Parent totals are summed from their children automatically.
- How many levels can I use?
- As many as you have columns, though rings past the third become thin. Two or three levels read best.
- Sunburst or treemap?
- A sunburst makes the hierarchy itself very legible. A treemap uses space more efficiently and is easier to compare by area. Both accept the same data here.
