At this point... I think we only have Susie Lu (Netflix)'s annotator, but good chance of it being removed. For example, we had to do our own timeline to get decently fast zoom rebinning on modern screen widths that we abandoned a JS widget here, and histograms ended up being so custom that we'd get little from a library. The shortlist for GIS is DecKGL. Graphistry gets a lot of requests here, so we helped the DeckGL folks on some Arrow/GPU stuff and we had promising experiments as part of it, but (if I remember right) we hit memory issues and something else. We'll be evaluating that for GIS next time it makes sense. +1 to others on HighCharts team!
