CHOROPLETH MAP

I had to include one more choropelth map which illustrates the Muslim population in Africa, 2005. I think it could be considered classed because the data has been divided into intervals and standardized because the data has been areally averaged to get a percentage. Based on this graphic, the Muslims seem to be more concentrated in North Africa.

CHOROPLETH MAP

A choropleth map is defined as a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map. This one shows alcohol related fatalities by county in Massachusetts for 2006. The legend reflects a range of the number of fatalities in each county. I think this is a great map for communicating these statistics and the website actually has lots more information including maps for all states.
