It took me a while to get the animation to work, but basically I combined a ggplot2 graph with plotly using ggplotly. ggplotly doesn’t support all features of ggplot2, for example rug plots are out, but it does quite a lot. I’m fond of thinking if you can make a scatterplot along with line segments and polygons, you basically can create any visualization you want (you might also need curves if you believe in them).
