The Visualizing Data for Human Rights Advocacy guidebook was launched by a group of the New York University (NYU) academics. The guidebook provides accessible information on collecting, compiling and visualizing data on human rights issues. Explained in simple language and geared to human rights practitioners, this guidebook was designed to facilitate workshop and training activities around designing effective data visualizations for human rights advocacy. Data visualization can make information more memorable and persuasive; it can facilitate understanding and ultimately motivate action. It can help investigators and researchers contextualize their work, and identify patterns and connections. When done well, human rights data visuzalization can uncover abusive policies, unlawful orders, negligence, or other forms of culpable action or inaction by decision-makers.
