I'm working on a basic choropleth map that visualizes one variable for all the counties in a single state. I want to create a map for each county that highlights (or adjusts the border style for) the relevant county boundary. The map will otherwise be identical, showing the whole state, the same variable classes, and so forth. If easier, other style tweaks that draw attention to a specific county would also be suitable. Maps will be used in printed documents.
I'm primarily using QGIS 2.1, but solutions that involve ArcGIS would be fine. Python or other frameworks are acceptable as well, but please reference some documentation if you can so that I'm able to brush up on relevant details.
I've looked into trying to use the QGIS Print Composer Atlas, but it doesn't seem that Atlas alone will yield a solution.
In other words, what's the best way to batch produce maps (to be exported as images) that stylize each individual polygon feature while maintaining the full map extent and other details?
