Assignment 7
PS 3780 Data Literacy & Visualization, Autumn 2021
Due Date: Friday, November 5, 2021 at 1:00 p.m.
Please save your visualizations and answers to these questions as one .pdf
le (use the save as function in most word processors). Be sure to include your name,
your teammate’s name if there is anyone, and the assignment number. Submit the le
to Carmen by the due date. Remember we are looking for professional visualizations so
please include a meaningful title as well as axis labels and a legend.
Part I: API and World Bank
1. Apply the World Bank API to extract female life expectancy data. Compare the
trends of the United States, the European Union, the entire World (this group is
included in the data) as well as a fourth country or collection. Write a paragraph
to describe the plot you created and explain which fourth option you included and
why. Make sure to include axis labels, a title, and a legend for your plot. (3 pts)
Some hints:
ˆ Use WDI() command from WDI package to implement the World Bank API,
and set indicator = SP.DYN.LE00.FE.IN in the parentheses. You can also
truncate data by setting start = and end = .
ˆ Create appropriate subsets and add lines to an initial plot. Set the ylim to
ensure that all cases are visible.
2. Repeat the prior question for a World Bank indicator of your choice – please choose
one for which there is enough data! Include the same countries / groups as in the
previous plot. In addition to describing the plot, make sure you dene the indicator
you used, with what unit it is measured, and why you chose it. Make sure to include
axis labels, a title, and a legend for your plot. (3 pts)
Some hints:
ˆ Use WDIsearch() to look for a particular indicator available from the World
Bank API.
ˆ Most of the plotting code from the rst part should work as long as you change
the appropriate dataset name, variable name, and ylim values.
