line9 · diagram rendering engine · v0.1
Diagrams, rendered properly.
The default Mermaid viewer produces diagrams that obscure more than they reveal. line9 is a new rendering engine — same source, honest output. Intelligent layout, semantic zoom, and an editorial sense of type.
§ 01
Why line9
§ 01
Layout that argues.
Intelligent placement, honest orthogonals, crossings minimised. Diagrams read like they mean it — no manual pushing of boxes.
§ 02
Semantic zoom.
Zoom into detail or out to the shape of the system. Labels, groups, and edges adapt at every level rather than scaling blindly.
§ 03
Type, not decoration.
Themes designed as typography, not palettes. Export to SVG, PNG, and PDF with the same care a typesetter would bring.
§ 02
Side by side
§ 02·01 Flowchart
Before Mermaid default — nodes collide, edges detour.
After line9 — straight reads, honest orthogonals.
§ 02·02 Sequence
Before Mermaid default — lifelines stretched, labels cramped.
After line9 — measured spacing, labels given room.
§ 02·03 Class
Before Mermaid default — relationships tangled, cruft visible.
After line9 — structure surfaced, hierarchy clear.
