Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain kinds of charts and when to use them, support designing clear and honest charts, describe specialised charts in fields, and identify misleading chart practices.

A graphical representation of data or information, such as bar, line, pie and scatter charts, diagrams such as burn up and burn down charts in project management, life expectancy charts, and scientific diagrams such as Amagat diagrams, used to reveal patterns, compare quantities and communicate findings; charts are built from axes, scales, marks and labels, follow conventions of data visualisation, and can mislead when badly designed.

What it is for: Graphical representations of data.

It can be explain kinds of chart; support designing charts; describe specialised charts; identify misleading practices.

Chart types

Design conventions

Potential to mislead

What it looks like

Graphics with axes, bars, lines, areas or sectors.

How it is recognised

Data shown graphically

Axes, scales, marks, labels

A map shows space; a table shows values in cells; a nautical chart is another sense
