What disappears inside a national average? →Countries can improve on average while wealth remains concentrated within one country. Compare the unit of observation before comparing the trends. Wealth shares and life expectancy measure different things.What does a visualization let you notice? →A color map controls how differences reach the eye. Moving bubbles can expose patterns over time. In both cases the encoding influences what viewers can detect.
Caption notes
Animated bubbles trace changes in income and life expectancy across countries. Rosling also shows how a national average hides internal differences.
