Module 8 - Cartography - Proportional Symbol Mapping

In this week's lesson, we made maps using proportionally-sized symbols to represent different values.  The first map displays wine consumption in thousands of liters for European countries (obtained from The Wine Institute).  We imported a simple image of a wine bottle in .png format, and used it in the symbology instead of different sizes of circles or squares.  This adds some interest to the map and immediately tells the viewer what it's about.
This map was done entirely in ArcMap.



The second may was started in ArcMap, and most of the work was done in Adobe Illustrator.  It concentrates on wine consumption in western European countries, using the same data that was used in the first map. We imported the same wine bottle image, and combined it with a circle into a single symbol using Illustrator.  In this case, the symbols are still proportional to wine consumption in each country, but we've shown the values next to the symbols, since there are only seven.  Again, using the proportinally-sized symbols, and the wine bottle symbology, is a very effective way to convey the data to the map viewer.
