Scatter plots
Scatter plots are useful for showing a general relationship between two variables and an
overall impression of the relationship.
Line graphs
Line graphs are good at showing trends over time. Use a line graph if the x-axis is an
interval scale such as days, weeks, or months.
A vertical bar chart could have been used for this, but the goal was to show the trend and the shape of the data
rather than the numbers. Here you can see the “M-curve” in the case of Japan. Many women in Japan drop out
of the workforce when they have children (and then reenter the workforce again later).
