Design Type: Tree map
Name of Tool: Tableau
Colour: maps to the sum of electricity capacity of the country.
Size: maps to the sum of electricity capacity of the country.
Unique Observation: China and USA lead by a substantial margin, quadrupling the 3 place’s (India) value. The differences from 3rd place and below are not too drastic which just shows how far ahead USA is in terms of development compared to the rest of the world.
Data Preparation: The gradient isn’t as effective because of the very large difference in values caused by USA. Therefore, I added numerical values to show the exact values of the capacity of each countries to help users truly see the difference.
