The gvisMotionChart() function has been broken since Adobe Flash reached end-of-life in December 2020. With Claude's help I've built a drop-in-style replacement called MotionChart (https://github.com/John-R-Wallace-NOAA/GoogleVis_Type_Motion_Chart_No_Flash) that replicates the core functionality using echarts4r and a JavaScript requestAnimationFrame loop - no Flash, no server, data stays local. Posting here in case it's useful to maintainers or users who land on this repo looking for a working solution.
