I think a line graph would best depict Flores del Mundo’s membership trends over the course of the year. This type of graph shows the shape of the data and is easy to understand at a glance. However, If we are interested in graphing total membership vs. detailed type (i.e., employee, spouse, or child), I would suggest a color-coded bar graph to show patterns and trends across each group. Using a line graph for this type of data may be cluttered and difficult to interpret. A line graph or a bar graph could be effective to Eastern and Northern membership trends on the same graph. In either case, sticking to a 2D plane would be best.
