expand_plot() is a convenience function that expands the scales of a ggplot, as the large node sizes in a DAG will often get clipped in themes that don't have DAGs in mind.

expand_plot(expand_x = expand_scale(c(0.1, 0.1)),
expand_y = expand_scale(c(0.1, 0.1)))

## Arguments

expand_x, expand_y Vector of range expansion constants used to add some padding around the data, to ensure that they are placed some distance away from the axes. Use the convenience function expand_scale() to generate the values for the expand argument.
