The client has a large and complex data organisation, with teams in multiple markets contributing different roles and products to the overall Big Data programme. They saw a static visualisation based on some IBM research and asked me to create an interactive equivalent to describe their own Big Data set up across multiple products, roles, and markets.
D3.js, and some help from David Johnstone's wonderful gradient picker for generating a smooth colour palette.
The client wanted non-technical team members to be able to update the data easily, as different markets came on board the programme, so we created a simple CSV data set.
The data used in this public version replicates the original IBM image.
