Brief
mapgl 0.5.0 for R introduces synchronized multi-map behavior: interactions in one map propagate to many linked maps in the same browser. In a June 26, 2026 demo, @kyleewalker showed 16 demographic maps for Atlanta kept in lockstep, with a laser-pointer indicating the tracked position; practical limits depend on browser performance.
Why it matters
mapgl 0.5.0 for R adds synchronized multi-map support, letting a single interaction keep multiple maps in sync across a browser
Key details
- Author @kyle_e_walker demonstrated 16 distinct demographic maps of the Atlanta area (video) where interacting with one map moves all 15 others and a laser-pointer tracks the position
- Capability is limited only by browser performance — you can create as many synced maps as the browser can handle, though author doesn't explicitly recommend a 16-panel layout
