Thanks for this, yes I think these could be good ideas. Just quickly on d) I meant it would be visually useful to see a table showing the data for the top 5 or 10 countries too, or else you have to hover over each country to see, and then you could show vs 2017 to see if there has been a large increase in a given country for example. Understandable about salary data, a shame though! Thanks a lot!
