Renderer-agnostic rubberband selection & multi-drag engine
Grew out of AntV X6 issue #4823: rAF coalescing, drag snapshots, and a preview/commit split. It exists to solve one concrete problem — dragging 100 elements should not drop frames.
Zero-dependency SVG graph-editing kernel
2,108 lines: semantic pins, orthogonal obstacle-avoiding routing, snapping, undo stack, JSON persistence. 49 unit tests plus 2 Chrome E2E suites.
One deterministically generated 20,000-node dataset, rendered with different engines across six interactive demos — all of them run live in the browser, each with a walkthrough video.
MapLibre + deck.gl · 20,000 nodes
Tiled mode delivers the first screen in 1.62 MB across 16 tiles; full-dataset mode pulls 8.86 MB in 53 ms. Both hold 60 FPS.
Three.js · click-to-place decals
Upload a GLB and artwork, click the model surface to place a decal that conforms to the geometry, then drag, resize, rotate and export.
