Unclassed vs. Classed

I want to reword my last graph posted graph on classed choropleth maps and discribe both of the classed and unclassed graphs on one blog posting. Like this one shows the differences in mapping and how the information is repersented. The maps and information is the same, but the way we look and understand the graph is different. The legend show on the side of the classed map shows what the differences of shading mean and how the transitions are different.http://gis.depaul.edu/shwang/teaching/geo381/LN9.htm
