+Dumbbell plots are useful for demonstrating change between two sets of data points, for example, the population change for a selection of countries for two different years.
 
 In this example, we compare life expectancy in 1952 with life expectancy in 2002 for countries in Europe.

 The second trace adds circle markers. On the first trace, we use `standoff=8` to position the arrow marker back from the data point.
