This map shows information about water utility ownership (public vs private) in the United States. The circles represent the 500 largest water utlities in the US and are scaled proportionally based on the population served. The state layer provides a summary of all water systems and is shaded based on the percentage of systems that are privately owned.

This thematic map shows the density of breweries in North America in a hexagonal grid (hexbins). The hexabins are shaded in proportion to the measurement of the statistical variable, in this case, breweries. Hexabin maps differ from choropleth maps in that equal-sized spaces, rather than political boundaries, are used.
The map was generated in QGIS using SQL and geometry tools.
