I would love to know if building something like this is possible is RShiny. I have experience with interactive plots/charts using plotly, ggplot and ggplotly but I can't see how to do something like this. I love how the graph engages the user to make a guess and then shows the real data.
If anyone could please point me in the direction of any documentation I will be forever grateful! https://www.mathematica-mpr.com/dataviz/race-to-the-top
