ChoroWare is a tool designed to help cartographers and map users find class
intervals for choropleth mapping. The initiative of ChoroWare is driven by a
multiobjective view of choropleth, an idea that can be found in the original
work of Jenks and Caspall (1971). There are many criteria that can be used to
make a choropleth map. However, it is often recognized that it is difficult to
find a criterion that can perfectly reflect the need of cartographers.
Sometimes, Jenks optimum may be the best criterion, while other times equal
interval is better. Therefore, one may wish to examine the trade-offs between
the criteria and then find a set of class intervals that can meet his/her need. 

We have developed a program that uses evolutionary algorithms to generate the
solutions of multiobjective choropleth (a solution is a set of class
intervals). The problem is: we may have thousands of good solutions but we do
not know which is the one. To address this problem, we developed a
visualization tool that can be used to help users go through the solutions and
interactively compare these solutions and finally find the best one.
