Choropleth Map: Unclassed

http://go.owu.edu/~jbkrygie/krygier_html/geog_353/geog_353_lo/geog_353_lo07.html
In an unclassed choropleth map, the areal data being conveyed is not grouped into intervals to make the distinguishable factors on the map more generalized. The number of intervals is equal to the number of areal units. The map above shows an unclassified chorpleth map, as a continuous grey scale is used and wherever each county falls is shaded in with its own color. It is a far more hectic view of the counties in our nation than it would otherwise appear if the map was classed, implementing less intervals.
