In paulnorthrop/stat0002: Introduction to Probability and Statistics

World Bank Development Indicators Movie

Description

Explores graphically relationships between four annual World Development Indicators provided in the World Bank's database for the countries of the world, 1960-2014. Animation is used to visualise how these variables and their inter-relationships vary over time.

Details

The example code in Examples below creates a scatter plot of data on the variables given by the first two arguments of the function, i.e. log(gdp_per_capita) and log(co2_per_capita). Each pair of values in represented by a circle. The area of the circle is proportional to the argument size, i.e. population_size and the argument col indicates the approximate value of the fourth variable, i.e. life_expectancy.

The scatter plot can be animated over years and points for an individual country can be highlighted in red by clicking the name of the country.

See rp.bubbleplot for more information.

This type of plot was used to great effect by Hans Rosling. To see Hans explain in simple terms the scientific and political issues surrounding these data see this video

Value

Nothing is returned, only the animation is produced.

# Produce the movie.  You may ignore the warning message that is produced.
# (I think the cause may be that some countries have a lot of missing data.)
