A data visualization style guide does for graphs what the Chicago Manual of Style does for English grammar: it defines the components of a graph and their proper, consistent use. In the process of revising and expanding the style guide for the Urban Institute, a nonprofit research institution based in Washington, DC, we are taking a more diverse, equitable, and inclusive (DEI) perspective to our research, data, and visualizations. Here, we discuss eight techniques that data visualization producers should consider when creating visuals. We consider this a first step in our process of creating graphs through a DEI lens.
