scale-size-manual
Manual discrete size scale: supply a per-level array of Typst lengths.
Use when each level should map to a chosen marker radius rather than the evenly-spaced range that the discrete inference would assign.
Usage

values: (),
name: none,
limits: none,
labels: auto,
)Parameters
| Parameter | Default | Description |

Examples
Three groups assigned small/medium/large markers.
#let d = (
(x: 1, y: 1, g: "a"), (x: 2, y: 2, g: "a"),
(x: 1, y: 2, g: "b"), (x: 2, y: 3, g: "b"),
(x: 1, y: 3, g: "c"), (x: 2, y: 4, g: "c"),
)
