You can use the search button (left panel top) to filter arcs by place/collection. The left panel functions more like map navigation, while the search/command palette is a separate mode.
Fair point, and a good idea. A visual marker distinguishing "has open data" from "doesn't" would meaningfully reduce that distortion. Adding it to the list.
Thanks! You actually can filter by source already, search lets you filter arcs by place/site. Destination filtering technically works too, via Collections, but that only makes sense while there are a handful, once it’s hundreds it’ll need its own proper destination filter. Good call on the color/gradient distinction for source vs. destination on the arcs too, that’s worth trying.
Fair catch, it only pulls from institutions with open access APIs (Met, V&A, SMB Berlin, AIC). Not aware of an equivalent from Japanese museums, if you know one, happy to add it.
Correct, scoped to western/euro-american museums as noted in the post, it’s just where I started. Open to expanding if there’s good open data to pull from.
