The first labyrinthine visualisation (above) uses data on directorial appointments and terminations to show links between companies under Tesco’s umbrella, with each line representing a particular individual and the subsidiaries at which they have been a director.
Lines are coloured according to the cluster of companies they join, with font and node size corresponding to the number of directors sitting exclusively on the board of the division concerned.
The cluster of interconnected companies in the bottom-right shows that a relatively small number of individuals have moved from one subdivision to another – often multiple times – over the period contained in the data.
These companies, most of which are named after colours, include property nominees such as Tesco Indigo and Tesco Fuschia.
This second graphic uses the same techniques but for data on Tesco companies’ registered addresses instead of directors.
Each line represents one company registered at the corresponding address. As you can see, several of Tesco’s subsidiaries have addresses in the Cayman Islands.
OpenCorporates is a public database containing a variety of information on businesses across the world. Addresses, UK Health & Safety notices and details of financial transactions are among the types of data available.
For more information on these graphics, you can find a step-by-step explanation of how the corporate structure graph was made and a brief guide to the address graphic at OUseful.
