Yeah, not a good way to visualize as the relationship between medal count and HDI is not obvious as only outliers get highlighted and the lack of information on other countries actually invite doubt as to the story that the plot is trying to tell (for example, Singapore and Hong Kong have extremely high HDI but the sheer smallness of their population is a factor against a higher medal count). There’s nothing wrong with a traditional 2D scatter plot and axis-related box plots plotted against each axis separately
