Nine mapped stores split Greater Brisbane into nine nearest-store territories

In brisbane show me a voroni diagram of the major supermarkets
One Voronoi (Thiessen) cell per mapped supermarket across the Greater Brisbane search extent — 9 deduplicated store coordinates from a live-web scan: Coles 3, Woolworths 2, ALDI 2, IGA 2 — coloured by chain, from Everton Park in the north to Mount Warren Park in the south and East Ipswich in the west.
Read this first: the scan covered 1,933 unique search results and 107 candidate pages, but only 9 locations had usable, deduplicated coordinates. Each cell means “nearest among these 9 mapped stores”, not a true market area, drive-time catchment, or a census of every Brisbane supermarket.
Coles is the only chain with three mapped stores, and its Mount Warren Park cell covers the entire south-eastern corner toward Logan and Beenleigh —
localmint.comWoolworths Everton Park holds the whole northern flank of the diagram as the northernmost mapped point —
localmint.comThe western third belongs to just two stores near Ipswich — IGA X-press East Ipswich and Woolworths Karalee — a sign of how sparse the mapped set is out west —
localmint.comThe inner city is the tightest contest: Coles at The Barracks and Seasons IGA Greenslopes sit about 6 km apart, giving the smallest cells on the map —

The nine mapped stores
| Chain | Store | Address | Lat | Lon | Source |

Live-web scan, February snapshot: 1,933 unique search results, 107 candidate pages, 9 deduplicated supermarket coordinates plotted (Coles 3, Woolworths 2, ALDI 2, IGA 2). Voronoi cells computed by Euclidean proximity on mapped coordinates, clipped to the displayed extent; they ignore roads, rivers, travel time, store size, and every store the scan did not resolve. A partial exploratory diagram, not an exhaustive census.
