Hits on the \(6 \times 6\) map. Each hexagon represents a node of the map. The size of the coloured hexagons scales with the number of traces that fall in each node. The nodes in a different colour than yellow emphasize the existence of a high clustering index (larger than 0.6) in a certain month: hot pink is for August, green is for September, and orange is for October and November.
