Migration Map is an Analysis tool that writes a self-contained animated HTML map (Leaflet) of how people and families moved over time. It reads every dated event whose place has coordinates, groups them per person in time order, and produces a timeline you can play: each person's path draws itself across the years, dots pulse on the moves happening that year, and a readout names who is moving where. Paths are coloured by surname. Pairs with the Geocode Places tool, which supplies the coordinates. All tree text is HTML-escaped before embedding and the Leaflet CDN assets carry Subresource Integrity hashes.

What it is
A Tool (Tools → Analysis and Exploration → Migration Map) that writes a self-contained, animated HTML map of how people and families moved over time, and opens it in the browser. It reads every dated event whose place has coordinates, groups them per person in time order, and produces a Leaflet timeline you can play: each person's path draws itself across the years, dots pulse on the moves happening that year, and a readout names who is moving where. Paths are colored by surname.
Requirements
Only places with coordinates appear. Run a geocoder first (e.g. the companion Geocode Places tool, or the Place Coordinate Gramplet). Events also need a year. The page loads Leaflet + OSM tiles from the internet (Subresource Integrity pinned).
Security
All person/place/event text is HTML-escaped before being embedded in popups; the Leaflet CDN tags carry SRI hashes.
Testing done
Verified on a real 868-person tree: event collection, the HTML/animation rendering (692 located events for 321 people, 1587–2016, rendered headlessly via a browser), and plugin registration as a Tool. The tool follows the standard
ToolManagedWindowBatch+MenuToolOptionspattern (modeled on AttachSourceTool). Reviewer GUI run welcomed before merge.Notes
Targets
gramps_target_version="6.0"/maintenance/gramps60; can port to 6.1.
