A stacked bar chart is a data visualization technique in which rectangular bars are subdivided into colored segments, each representing a proportional part of a whole. The total length of each bar encodes the sum across categories, while the internal segments encode individual category contributions. Parameters: (1) a categorical axis dividing bars by group, (2) a quantitative axis encoding magnitude, (3) segment coloring to distinguish composition parts. Persistence mechanism: analytical reporting, comparative visual communication, and statistical practice. [formal: charta stipata | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.26]

Definition
Why it is in scope
A human-made data visualization technique that represents quantitative data as rectangular bars subdivided into segments, where each segment represents a proportional part of a whole and the total bar length encodes the sum across categories. Built to persist through analytical reporting, comparative studies, and visual communication practice.

A stacked bar chart IS a specific kind of bar chart: it uses the same basic bar encoding but subdivides each bar into compositional segments. A competent speaker would call a stacked bar chart 'a bar chart.' The INSTANCE_OF direction is correct: specific (stacked bar chart) → general (bar chart). Direction pinned per Law 11d: 'stacked bar chart' as a compositional bar chart variant.

TESTED INSTANCE_OF: A stacked bar chart IS a specific kind of plot — it displays quantitative data using rectangular bars with widths proportional to values, grouped by category, with segments stacked vertically or horizontally. A competent speaker would call it 'a plot'.
