chart

A chart IS a specific kind of data visualization — it encodes data into a structured visual form. A competent speaker would call a chart a type of data visualization. Specific→general INSTANCE_OF to nearest kind.

chart INSTANCE_OF diagram. A chart is a specific kind of diagram — a visual representation of data or information using graphical elements. A competent speaker would call a chart 'a diagram.' The diagram entry is the nearest kind; no intermediate rung exists between chart and diagram.

a chart is a specific kind of tool — an artifact that extends human capacity for visual data comprehension. Per Law 11c, passive artifacts (shelves, jars, walls) qualify as tools; a chart extends data comprehension capacity.

A legend is a literal part inside a chart — it identifies which data series corresponds to which visual encoding. Whole-and-part relationship (Law 10).

Small multiples is a specific chart technique consisting of multiple related charts arranged in a grid. Specific→general kind relation.

Direction tested: INSTANCE_OF (specific→general). A pie chart IS a specific kind of chart — a circular statistical graphic divided into slices to illustrate numerical proportion. A competent speaker would say 'a pie chart is a chart'.

A tree diagram is a specific kind of chart — a graphical representation of a hierarchical structure. A competent speaker would say 'a tree diagram is a chart.' Meets Law 9.

chord diagram IS a specific kind of chart — a circular chart showing relationships between data pairs. Competent speakers call chord diagrams 'charts.'

A scatter plot matrix is a specific kind of chart: a grid/array of scatter plots showing pairwise relationships across multiple variables. Nearest kind is chart (both epoch 0.31, chart is more foundational). Sense: scatter plot matrix as a multi-variable chart type.

A bar chart is a specific kind of chart that compares categories using rectangular bars proportional to their values. A competent speaker calls a bar chart 'a chart'.

A trellis plot (small multiples) IS a specific kind of chart: it displays multiple subplots of the same variables across facets of a conditioning variable. Per Law 9, a competent speaker would call it 'a chart.' Nearest kind is chart.

Pictogram is a specific kind of chart: a visual representation that uses pictures or simple drawings to convey information. A competent speaker would call it 'a chart' or 'a type of chart'. Per Law 9, specific→general direction.

A line chart IS a specific kind of chart — it displays quantitative data using a series of data points connected by straight line segments. Specific→general INSTANCE_OF against the nearest kind (chart). The epoch tie (0.31 vs 0.31) does not change the kind relationship.

Sankey diagram IS a specific kind of chart: a visual representation of flows between entities, where the width of arrows or lines is proportional to the flow quantity. It visualizes the movement of resources, energy, or materials through a system.

A plot is a specific kind of chart — a graphical representation of data points. Competent speakers use 'plot' and 'chart' interchangeably for data visualizations (scatter plot = scatter chart). Chart is the broader category (epoch 0.31, plot epoch 0.88). Nearest kind: no tighter category between plot and chart exists.

A funnel chart IS a specific kind of chart: it visualizes stages of a process (e.g. sales pipeline) as stacked, decreasing-width shapes. A competent speaker would call it a chart. Nearest kind is 'chart'. Law 9.

contour plot IS a specific kind of chart: a data visualization using contour lines to represent 3D surfaces on 2D space. Per Law 9: specific→general. A competent speaker calls it 'a chart.'

TESTED INSTANCE_OF: a confusion matrix IS a specific kind of chart — it visually presents a tabular layout of true/false positives and negatives, typically rendered as a heatmapped grid. Specific→general, nearest kind is chart (not classification — that was my prior error; a confusion matrix evaluates classification but is not itself a classification).

An ROC curve is a specific kind of chart — a two-dimensional plot with TPR on y-axis and FPR on x-axis. A competent speaker calls it a chart. Files against nearest accepted kind 'chart'.

Charts (general data visualization) predate radial charts as a specific chart type. The general form came first, and radial charts are a specialized derivation. Which came first? Charts.

A choropleth map is a specific kind of statistical chart that uses color-coded geographic regions. A competent speaker would call it 'a chart.'

A choropleth map is a specific kind of chart — a geographic visualization where areas are shaded according to data values. Per Law 9, 'X is a specific kind of Y' is INSTANCE_OF; a competent speaker calls a choropleth map a type of data chart.

A pareto chart is a specific kind of chart that combines descending-frequency bars with a cumulative-percentage line. Per Law 9, 'X is a specific kind of Y' is INSTANCE_OF. A competent speaker would call a pareto chart 'a chart.'

Law 9: specific→general. A run chart is a specific kind of chart — a line chart of sequential data used to detect trends and shifts. A competent speaker would call a run chart 'a chart.' Direction: run chart (specific) → chart (general).

An x-bar chart is a specific kind of chart used in statistical process control. A competent speaker calls it a type of chart.
