Figure 1.
The map of Ireland displays county boundaries with two sets of circular point markers. One cluster appears across Northern Ireland and much of the western and north-western regions. The second cluster appears across the Republic of Ireland, especially the east, south, and south west. Both clusters overlap in some central border areas. Marker density is highest around the eastern coast near the Dublin region and several southern urban areas. Northern and western coastal areas have fewer markers and wider spacing.Map of Ireland with location of hubs in the connected hubs network. Green
