One thing the graph doesn't represent is how often a particular train stop is serviced.
As an example, since (August?) of 2005, Atherton only has weekend and special event caltrain service. You could argue that shouldn't be surprising given the graph (median income of ~$193K), but it's still an important piece of missing information.
It would have been nice to see a graph based on total number of stops scheduled for a station overlaid with the median household income as it is currently graphed for caltrain.
