Untitled string in Mermaid Config Schema

https://mermaid.js.org/schemas/config.schema.json#/properties/elk/properties/preset

Named combination of layering, node placement, placement alignment and cycle breaking options. Explicit options override the preset for that option; the remaining preset values still apply.

default — network simplex layering, balanced Brandes-Koepf placement at the top level and inside subgraphs, and depth-first cycle breaking. Balanced placement favors centered branches and composite-state entries, sometimes at the cost of a wider or taller drawing. It does not guarantee that every edge attaches to the center of its target.

legacy — Brandes-Koepf placement with NONE alignment and ELK's own greedy cycle breaking. Reproduces the rendering before presets existed.

modelOrder — network simplex layering and top-level placement, Brandes-Koepf placement inside subgraphs, NONE alignment, and greedy model-order cycle breaking, which favors declaration order.

depthFirst — the previous default: network simplex layering and top-level placement, Brandes-Koepf placement inside subgraphs, NONE alignment, and depth-first cycle breaking.

Setting layeringStrategy, nodePlacementStrategy, nodePlacementAlignment or cycleBreakingStrategy explicitly overrides the preset for that option, including an explicit NONE alignment.
