Dot Matrix Chart

Source: Data Visualisation Catalogue - Dot Matrix Chart

Why This Belongs In The Compiler Gallery

Dot matrix charts test repeated-symbol layout. The visible marks are ordinary point glyphs, but the compiler needs to expand raw category counts into repeated dots with stable row/column positions.

Data Contract

Each raw row is one category total.

FieldTypePurpose
categorycategoricalRow/group label.
valuequantitativeCount represented by repeated dots.
representedValuequantitative, derivedValue represented by an individual dot.
cx, cy, rquantitative, derivedDot geometry.

Expected Visual

Each category renders as a compact grid of same-size dots. The first gallery version uses one dot for up to five units, preserving source-row lineage on every generated dot.

Compiler Mapping

Compiler partMapping
Data sourcecategory-counts raw rows and derived matrix-dots.
Transformlayout with layoutKind: "dotMatrix" expands each count into repeated dot rows.
Scalescategory: band for labels, color: ordinal(category) for dots.
LayersCategory labels and point glyphs.

Faithfulness Notes

The core repeated-dot expansion is compiler-owned now. Remaining work is a richer symbol template system for pictograms/tally charts, plus exact remainder policies and responsive dot packing.
