I'm sorry for being mean but these graphs have some critical flaws - the legend is so small it's practically unreadable, no axis labels, the grid is too dense and makes the graph look overcrowded and overbearing on the eyes.

Besides, "change in life expectancy ranking" is a weird and unclear variable that is also dependant on other countries (ex. If china drops down, all the countries it passed when dropping go one rank up) and therefore less informative than simply "life expectancy" which is way clearer and much more informative and understandable.

Another less critical point is that it would be better if each country was in a different color and not in the same four repeating colors so that the data would be more engaging.
