Mass-spring graph: nodes repel each other (Coulomb) and are held by Hooke springs on defined edges. By default a settled, static layout computed server-side, so it works everywhere, including print and assistive tech. Drag-to-pin with live springs is opt-in with interactive: true.
| Field | Type | Required |
|---|---|---|
| nodes | array. Array of {id, label} objects. Defaults to 6 labelled nodes. | optional |
| edges | array. Array of {a, b} index pairs for spring connections. | optional |
| colour | string. Node and edge accent colour. Default | optional |
| bg | string. Background colour. Default | optional |
| height | integer. Canvas height px. Default 420. | optional |
| rest_length | integer. Spring rest length px. Default 110. | optional |
| interactive | boolean. Default false: a settled, static layout that works everywhere and for assistive tech. Set true when the atom is shown in a live browser or app view and the viewer should be able to play with the graph: drag nodes to pin them, watch the springs react. Ignored under reduced motion and on static surfaces (print, slides, email, chat, and any surface that strips scripts). | optional |
