just for grins, i translated the Joro observation time series maps into a short video: https://youtu.be/ispwkQKQ23M. this is similar to some of the visualizations discussed in: https://forum.inaturalist.org/t/map-animation-of-observations-over-time/1217.
there was also an earlier visualization of the spread of SLF using the iNaturalist “experimental compare tool”: https://forum.inaturalist.org/t/map-showing-spread-of-spotted-lanternfly-since-2016/6377. i thought visualizing time series data was a clever application of that tool.
