Since Chrome will stop allowing Flash in the next month, I'm checking to see if anyone has any updates on an HTML5 alternative to the Google motion chart. I don't think Daniel LaLiberte has posted anything about it since 2018.
I've depended on this chart (with lotsa help from the googleVis R package) for many public presentations of my research. To preserve a record of what I built using it, I made this demo video:
https://youtu.be/Ps0wSv-D2Zg. It will feel like such a loss when it stops working!
FYI, "polyarchy" is a measure of democracy.
Also, someone on GitHub posted this alternative a few years ago. It still works, even without allowing Flash:
https://www.google.com/publicdata/directory. So it looks like an alternative exists, even if it isn't available to developers.
I can make something basic with shiny, but it would lack many of the great features the Google motion chart has. Or had.
