Choropleth Maps Without Class Intervals?: A Comment

Illuminated Choropleth Maps

Choropleth maps are commonly used to show statistical variation among map enumeration units. Map makers take into account numerous considerations and make many decisions to produce a product that will effectively communicate spatially complex information to the map user. One design consideration is the choice between classed or unclassed choropleth maps. Unclassed maps assign a unique color, sh...

Choropleth Maps: Classification Revisited

Classification was traditionally used as an instrument for producing choropleth maps. In our study we consider the role of the process of classification in exploratory data analysis. We developed a set of tools for classification that facilitate looking on data from various viewpoints and thereby investigate different aspects of the data. The tools include direct manipulation controls for speci...

Conditioned Choropleth Maps And Hypothesis Generation

Dynamic Queries and Brushing on Choropleth Maps

Users who must combine dcmographic, economic or other data in a geographic context are ofren hampered by the integration of tabular and n w p representations. Static, paper-based solutions limit the amount of data that can be placed on a single map or table. By providing an effective user interface, we believe that researchers, journalists, teachers, and students can explore complex data sets m...

Interactive Linked Micromap Plots And Dynamically Conditioned Choropleth Maps

This paper introduces interactive extensions to two recently developed templates for displaying geospatially-indexed estimates. The first template, linked micromap plots, links small generalized maps with statistical panels that describe regions. Research centered at the National Cancer Institute addressed the task of communicating state and county cancer statistics and tailored this template t...
