bar family
bar-grouped
Multiple bars per category, grouped side-by-side.
Two or more series per category, sitting next to each other instead of stacked. Each bar in a group has its own value to compare against the others. Better than stacked when individual segment comparison is the point.
When to use
Comparing 2–4 series across few categories where you want each value readable, not just the total.
When NOT to use
You have 5+ series (becomes cluttered) or need to show a sum (stack instead).
