I think the line graph shows a quick and simple view of what we are looking for in the membership graph. I still think I would like to see the line graph representing total membership for Employee/Spouse/Dependent, only because I like to present a graph that doesnt need to have a lot of time spent in explaining it. Not necessarily, I would say if we were showing many more regions or had the data spread out more, I would change the graph to a pie chart to make it easier for presentation, but I like the presentation as it is.
