Jamaican Slave Revolt
This animated thematic map narrates the spatial history of the greatest slave insurrection in the eighteenth century British Empire. It was a collaboration between Axis Maps and Vincent Brown at Harvard University.
revolt.json contains all the attribute and spatial data used in the map. The animated marker paths are defined by
LOC as an array of lat / lon arrays.
The map is built on Leaflet. The animation is handled by AnimatedLine.js which is based on Leaflet.AnimatedMarker. Like AnimatedMarker, AnimatedLine breaks an input PolyLine into small segments, then over a specified interval "grows" the PolyLine by including each of those segments in sequence.
