A grouped bar chart is a data visualization technique that organizes quantitative data into rectangular bars arranged in clusters, where each cluster corresponds to a category on the horizontal axis and each bar within the cluster represents a subcategory or series. The chart encodes two dimensions of categorical data: the primary category (grouped along the axis) and the secondary category (differentiated by bar color or position within the group), with bar length encoding a numerical value. It persists as a visual encoding convention standardized in information design and taught through data literacy curricula, charting libraries, and spreadsheet applications.

Definition
Why it is in scope
A human-made data visualization technique that displays comparisons across categories using bars grouped side-by-side for each category value. Each group contains separate bars for subcategories, enabling direct comparison within and between groups. It persists through charting libraries, spreadsheet software, and data analysis tools as a standard visualization pattern.

Direction test: specific→general. A grouped bar chart IS a specific kind of bar chart — bars arranged in clusters to compare multiple categories side by side. A competent speaker would call a grouped bar chart 'a bar chart'. Nearest kind: bar chart (bar chart→chart already ACCEPTED, so chart is not the nearest kind).

TESTED INSTANCE_OF: a grouped bar chart IS a specific kind of plot — a bar chart displaying multiple series of data with bars grouped side-by-side for each category. It is a visual representation of data.

A grouped bar chart is a chart type that builds on the bar chart mechanism. It requires bars as its fundamental visual encoding element — grouped bar charts organize multiple bars per category using the bar-length encoding. Remove bar charts and grouped bar charts cease to function.
