Lab 8

This was a lab on proportional symbols. We pretended that the state of Maryland asked us to create a grey-scale map (we haven't had our color lesson yet) depicting the relative density of census data for each county. In a proportional symbol map, a symbol (cow) is scaled to various sizes to depict the relative magnitude of some value. Proportional symbol maps scale symbols to continuous sizes. Graduated symbol maps only scale symbols to discrete sizes.
