Although this difference might be identified from the choropleth maps
, we believe this information is more quickly accessible from the PCP, even by novice users.
The design and production of choropleth maps
are relatively streamlined because of well-established data-symbolization techniques.
The LISA cluster maps of age-adjusted mortality rates for all causes at the beginning and end of the study period recapitulate the pattern observed in the choropleth maps
, but reduce the complexity so that statistically significant clusters can be more easily distinguished.
best demonstrate the changing prevalence of HIV among recruits from each district.
The choropleth maps
of two-bedroom rents are visually straightforward.
Legend Designs for Unclassed, Bivariate, Choropleth Maps
These maps demonstrate two types of cartographic methods--a choropleth map
and a diagram map (Kanok 1999; Vozenilek et al.
Second to choropleth maps
, the most common type of thematic representation was flow arrows.
Additionally, some cartographic methods require an equal-area base, for example, choropleth maps
(showing values usually normalized by area by differently shaded areas) or dot maps (where the relative density of dots changes with a real distortion).
Using genetic algorithms to create multicriteria class intervals for choropleth maps
Optimal Data Classification for Choropleth Maps
, Occasional Paper No.
More specifically, we report on "change blindness" and "change blindness blindness," and how these perceptual phenomena can reduce the effectiveness of animated choropleth maps
But for many statistical summary variables in ratio scale, using choropleth maps
is preferred, and methods focusing on symbolization may not be too effective.
of these SOM classes would therefore also be very similar to the bicomponent maps in Figure 7a.
The census EDs visualized through choropleth maps
present the ecological fallacy that all observations within an area are similar to the average for the area.
