A. Objectives

By the end of this lesson you should be able to:

  • Identify the data representations that are effective for mapping count data.
  • Indicate why choropleth maps are not good representations for count data.
  • Produce effective small-scale thematic maps for count data.
  • Construct a layout using multiple data frames with visual hierarchy that appropriately fits with the information to be read.

B. Project Overview

This is the second week examining issues related to presenting data for thematic display and working with the Philadelphia crime data. In week 1 you learned about classifications and choropleth maps. This week we will discuss and use other map representations, especially those that are better for representing count data (rather than rates as you used in your choropleths). Your task this week is to create a series of maps (on one layout) using different kinds of data representations that portray different aspects of the Philadelphia burglary data.
