Figure 2. Network of COVID-19 cases based on its centralities value and attributes.

Arrowheads indicate the direction of transmission from the source node to the target node. In Figures 2 (i) degree centrality, (ii) harmonic closeness centrality, and (iii) betweenness centrality, node size is ranked according to centrality value mentioned in each of the subfigure, increasing in size and value accordingly. Figure 2 (i): Males were represented by blue nodes, while females were represented by pink nodes. Figure 2 (ii): Blue-coloured nodes denoted Malays; purple-coloured nodes denoted Orang Asli (Aboriginal); red nodes denoted Chinese; green nodes denoted Indian; and grey nodes denoted others (foreigners). Figure 2 (iii): Nodes coloured pink denoted Malaysians, while green nodes were non-citizens.
