Figure 3 depicts the groupings associated with the Enterprise Data Centre and Colocation Providers market categories. Since both categories have multiple groups in common, they are depicted in a horizontal tree diagram. Each category is a root node of the tree, with the Enterprise Data Centre category on the left, the Colocation Providers category on the right, and most of their common groups shown as nodes between them. The remaining groups are displayed on the left and right outer edges of the tree.
Each group depicted has a link associated with it that, if clicked, will take you to the corresponding section of the website.
