Spec: Charts (Layer 09)

File: src/layers/09-charts.css

Purpose

Data visualization using pure CSS and HTML tables. Inspired by Charts.css — uses data-* attributes to transform tables into visual charts.

Scope

In scope

Bar charts (horizontal and vertical)
Line charts
Area charts
Radial/gauge charts
Chart axes, labels, legends
Responsive chart sizing
Chart color schemes using design tokens

Out of scope

JavaScript-powered charts
Interactive chart features (tooltips on hover are CSS-only)

Lineage

Inspired by Charts.css data-* attribute pattern. Not a port — reimplemented for ASW's token system and semantic approach.

Constraints

References only semantic aliases from 01-tokens.css
Charts must be readable without CSS (the underlying table has the data)
Color choices must work for colorblind users
