The Supermarket Voronoi Map

I've been seeing a lot of Voronoi diagram maps lately, most of them created with D3.js. For example, Jason Davies has been creating to a greater extent than or less real interesting Voronoi maps with D3.js, including this much shared World Airports Voronoi.

However I haven't seen many attempts silent to purpose a Voronoi diagram with i of the psyche interactive mapping platforms. Chris Zetter has published a real cool tutorial on how you lot tin larn almost Building a Voronoi Map with D3 together with Leaflet. The tutorial is accompanied past times a prove map of Great Britain supermarkets.

The Supermarket Voronoi Map is a map which divides the Great Britain into a issue of regions. Each part contains i supermarket, where all the locations inside each part are closer to that supermarket than whatsoever other.

Using supermarkets for the demonstration map is a bang-up idea, equally it actually helps to choose the usefulness of Voronoi maps. Shoppers tin purpose the map to discovery their nearest supermarket. You tin fifty-fifty select an private chain of supermarket to discovery the nearest branch. For event you lot could purpose the map to discovery your nearest Waitrose.

You tin meet how a Voronoi map could likewise hold out real useful to the Supermarket chains themselves. The larger regions on the map could hold out used (probably amongst a population layer) to position untapped markets together with possible areas for siting novel stores.
