The above map represents the Percent Population with below Poverty Status (2009) in the City of Gainseville, Flordia. One issue with this map is the color scheme. Qualitative schemes, like the one used, are best suited to represent nominal or categorical data, not to imply magnitude differences between legend classes. A sequential scheme with one or two hues would have been more effective at representing the data. Another issue with this map is that it lack any sort of scale. Furthermore, the title to the map is not centered, and could be created larger in order to stand out more.
