The strategic diagram uses density on the vertical axis and centrality on the horizontal axis. Four labelled bubbles occupy different positions. Diffusion, with a value of 6, lies in the upper left at high density and low centrality. Reviews, with 74, forms the largest bubble and lies in the upper right at high density and high centrality. Trust, with 13, lies to the right of the vertical axis and close to the horizontal axis. Tourism, with 9, lies on the vertical axis below the horizontal axis at low density.Strategic diagram (2007–2015)
