Figure 2From: BiFold visualization of bipartite datasets BiFold bubble plot of US presidential election voting - by state (1976-2012). The BiFold layout based on state voting records, where \(b_{ij}=1\) if state i voted for the winning candidate in election j. Bubble size (area) is proportional to the number of states at that position, with the smallest circle indicating one state. Each two-digit year is positioned at the BiFold coordinates of the elected president.Back to article page
