Hierarchy Chart

Hierarchy charts visualize proportions within categories, making it easy to compare part-to-whole relationships.

• Treemaps use nested rectangles sized by value.

• Packed bubbles use circles sized by value.

Treemap

• Color → Dimension or measure for rectangle shading.

• Size → Measure to define rectangle area.

• Label → Adds text to each rectangle.

• Detail → Adds extra breakdown inside each rectangle.

• Color → Dimension or measure for bubble shading.

• Size → Measure to define bubble size.

• Label (optional) → Annotates each bubble with text.

• Detail (optional) → Adds extra grouping dimension.

Tips

• Both visuals are best for part-to-whole comparisons.

• Use Size for your main quantitative field.

• Detail lets you drill into a second dimension.

• Avoid too many small values—they can create clutter and make shapes too small to interpret.

• Use Color sparingly: too many categories can overwhelm the chart.
