研究方向

The issue requests a way to trigger a zoom event to redraw drops upon data change. To address this, first examine the EventDrops source code, particularly files handling zoom interactions (likely in src/ or lib/ directories). Identify how the drop rendering is tied to zoom transforms (e.g., via d3.zoom().on('zoom', ...) ). Then investigate where data changes are currently processed and whether they already trigger a redraw. If not, a new method or event emitter may need to be added to propagate data changes to the zoom behavior. Review any existing tests for zoom to understand expected behavior. The issue is old and lacks detail, so clarifications from maintainers may be needed on the desired API.
