As part of the Data for Decisions to Expand Nutrition initiative, Results for Development Institute conducted a landscape analysis of global data visualization tools and a literature review of data visualizations. They found that increases in available nutrition data can present challenges such as knowing which data are most critical for decision-making. Data visualization tools should lessen such challenges by serving as the interface between data and data users. After reviewing 22 tools, the authors identified inefficiencies in the data visualization tool landscape. This article suggests ways that improving such tools and their coordination might improve the uptake of data for nutrition decision-making.
