When to use this template

This visualization effectively highlights the proportional contribution of different categories to a national total, making it easy to discern which components are dominant or negligible. An analyst would use it to quickly understand the relative distribution of a single metric across a defined set of segments within a national context, identifying key drivers or areas of concentration.

• Datasets with a single categorical dimension representing parts of a whole.
• Data where values are non-negative and sum to a meaningful total.
• Low cardinality for the categorical dimension (typically 2-10 segments).
• Data representing proportions or percentages of a national aggregate.
• Snapshot data, not time-series, for a single point in time.
• Data where the relative size of each segment is the primary insight.
