Vertical Mapper was used to create a Natural Neigborhood (Voroni) diagram for McDonald's Restaurants (marked with stars) in San Francisco.
The edges of each area (also known as a Thiessen polygon) are equidistant between adjacent outlets.
This technique can be used to select locations that maximize distance from sister stores or competing ones.
Thiessen polygons create a sense of a chain's location strategy and provide a tool to visualise the effect of potential changes in strategy.
