Choropleths are thematic maps where geographic regions, such as states, are colored according to some metric, such as the number of people who live in that state. This package simplifies this process by 1. Providing ready-made functions for creating choropleths of common maps. 2. Providing data and API connections to interesting data sources for making choropleths. 3. Providing a framework for creating choropleths from arbitrary shapefiles. 4. Overlaying those maps over reference maps from Google Maps.
Contains an administrative-level-1 map of the world. Administrative-level-1 is the generic term for the largest sub-national subdivision of a country. This package was created for use with the choroplethr package.

The shapefile is taken from the US Census Bureau's 2013 Cartographic Boundary Shapefiles - ZIP Code Tabulation Areas (ZCTAs). See ?zip.map for additional information. Metadata about each ZCTA is in ?zip.regions. Metadata includes State, County and Metropolitan / Micropolitan Statistical Area (MSA).

Contains data and visualization functions for USA unemployment data. Data comes from the US Bureau of Labor Statistics (BLS). State data is in ?df_state_unemployment and covers 2000-2013. County data is in ?df_county_unemployment and covers 1990-2013. Choropleth maps of the data can be generated with ?state_unemployment_choropleth() and ?county_unemployment_choropleth() respectively.
