Convenience wrappers over D3 selections adding appendMany, translate, at/st shorthands and tspan wrapping.
Time-based event series visualisation showing dense dot timelines per row, with zoom and brushing.
Drop-in replacement for d3-force using random vertex sampling for linear-time layouts on large graphs.
UpSet plot implementation for visualising intersections across many sets where Venn diagrams break down.
