We love this map because it brings a bold aesthetic to otherwise basic point data. It was designed as a large wall hanging (17 ft or more than 5 m wide!) for a brewery tasting room. Here we see an innovative use of the Dorling cartogram approach, a technique for mapping thematic data. It allows the data to be summed up by country and mapped in an eye-catching, abstract way with beautiful symbology.
Bottle tops are scaled as proportional symbols to show the number of breweries per country. This cartogram works because it quickly gives us a sense of the major brewing nations organized by geographical areas and positioned to mimic a world map. Minimal text provides labels and numbers. The bottle tops appear to be strewn across a table, yet are carefully illuminated with a light source from the top left.
Locations of breweries, as addresses, were geocoded to add latitude and longitude that could then be mapped.
A proportional symbol map was made; symbols were converted to features and repositioned with a little manual editing.
The bottle top symbols are, in fact, a number of layers of symbols (bottle top, flag, text). Several styles were constructed and the Match to Style renderer used to symbolize countries.
Three layers of actual locations were symbolized with different sizes of dots and transparencies to build up the clusters on the hemisphere maps.
The background tabletop is a large graphic added to the layout.
The data was used with permission from beerme.com. The addresses were downloaded as a text file and geocoded to add latitude and longitude that could then be mapped. The country attribute was used to calculate totals for the cartogram symbol sizing.
The data was run through the ArcGIS World Geocoding service to add latitude and longitude and totals per country were summed. The coordinates and totals became the mappable information.
It takes about two hours to download and convert the addresses. This includes checking and verifying accuracy. The cartogram takes about three hours to build, including manual editing of symbol placement. The symbols take the most time, though many are built from the same primitives and can be applied to the map using data-driven symbolization.
Experiment to make sure the smallest symbol can be seen and the largest does not take over the map. Scaling isn’t linear but the overall effect is still visually engaging.
Processing data into different forms gives you flexibility to map it in different ways. Locations are used here in the inset rather than the main map. Often the interesting story is revealed by processing data this way.
Clients who want maps that provoke exploration and conversation give you the opportunity to be creative. Designing highly abstract wall maps is one fun way to stretch your artistic imagination.
Print isn’t dead! Maps don’t have to be on the web. As art, they look great on a wall.
