The bar chart in the People & Planet section of the vendor page is based on the same algorithm as the vendor level. The purpose of the bar chart is to show the relative focus on different types of stakeholders: Customers, Workers, Suppliers, Community and the Environment. Each vendor has its own story and the bar charts will differ. No vendor is expected to focus equally on all categories.
For example, the below vendor is a fair trade organization that focuses on benefiting suppliers.
And the below vendor is an organic farm that works closely with the surrounding community, but does very little with suppliers.
