Map 2: a frame per day
One frame per day (at twice the frame rate), changed the colour, location markers sized according to time spent at that point on that day (frame). Marker area = log (days spent there +0.5).
Map 3: a frame per year, 1199–1216
How I did this
Using Python with the Pandas library for data processing, Cartopy library for mapping and ImageMagick at the command line for stitching the frames together into a gif.
