29 Gapminder: 200 Countries, 200 Years
29.1 Introduction
In this project, you will recreate single year versions of the chart Hans Rosling shows in the videos here:
Gapminder, 200 Countries, 200 Years, 4 Minutes
The plots in both have the same information shown: income, life expectancy, population, and the continent.
29.2 Data files
The four files that you will need, downloaded from https://www.gapminder.org/data/, can be found in the “data” folder of this project.
There are CSV files for the following:
Income: “income_per_person_gdppercapita_ppp_inflation_adjusted.csv”
Life expectancy (years): “life_expectancy_years.csv”
Population: “population_total.csv”
In addition, there is an Excel file that you’ll need to use to get the region (continent) that each country is in. Use the variable “four_regions” for the continents.
