LinkStyle
LinkStyle =
"line"|"half-arrow"|"none"
Defined in: network/glyphs.ts:174
How links are drawn: plain "line" + a separate arrowhead (directed), a fused "half-arrow"
(the map glyph), or "none" — a nodes-only network (#157). "none" skips building the link /
arrowhead / super-edge geometry altogether (see drawsLinks); it is a rendering choice
only, so the edges still drive the force layout and the LOD hierarchy.
