– choropleth map symbolizes derived data such as average income or population density based on administrative boundaries Type of Map
Type of Map Quantitative – dasymetric map uses statistics and additional information to delineate areas of homogeneous values, rather than administrative boundaries.
– graduated symbol map uses different sized symbols to represent different magnitudes. Issues of range and discernable differences
– chart map uses either pie or bar charts to compare multiple sets of quantitive data. Size can be part of information
– flow map displays different quantities of flow data by varying the width of the line symbols Typography
