Fig. 3: The synergy and trade-off networks at the goal level built upon ABS(R) and Ratio.

The thickness of the edge in the network indicates the synergy or trade-off intensity among goals. The thicker the edge is the stronger the intensity is. The size of the circle suggests its importance as a central hub in the network. The larger the circle is, the more important the node as a central hub is. (a) is for synergy (hub score: 0.16−1) and (b) is for trade-off (hub score: 0.14-1). In the synergy network the edge is shown in blue and in red in the trade-off networks. Different colors indicate different SDGs following the official UN color palette.
