Lab 1 Part 2 - 3 Maps

This is a choropleth map. It uses different colors to help quickly visualize general data trends over larger areas (in this case counties). Choropleth maps may contain contrasting colors, a color scale, or a monochromatic scale.

Dot-density maps, like the one above, use a predetermined shape, color, and scale (in this map, 1 dot for every 100,000 people). This map uses concentration to show data trends over an area. The more data (in this case the higher the population) there is in an area, more corresponding dots there will be in that area.

This last map is called a proportional symbol map. It uses a fixed shape of a fixed color, but the size changes in proportion to the amount of data. Thus, the more data there is in an area, the larger the shape in that area will be. In this case, the more the forest industry in a country produces, the larger the dot for that country.
