Data visualisation has become ubiquitous in everyday life, from seeing images in news media to tracking individual health indicators. While the effects of data visualisation on society and people have been explored within a range of literature, there has been far less attention paid to the interconnectedness of data visualisation and policy making. In this special issue, we explore how data visualisation matters for policy priorities, processes and outcomes; how it reflects the demands and constraints posed by specific policy problems; and finally, what data visualisations reveal about broader political, social, and cultural shifts and the implications for policy.

These are outside the scope of the data, but we include discussion of some of them in the case study section. 14 "Regional Economic Communities (RECs)." 15 "Peace and Security Council Report No 113," 4.

Parties to peace agreements have long considered human rights as central to the consolidation of peace and democracy in post-conflict settings. Yet, understanding of the formal institutional mechanisms that peace processes put in place to promote and protect human rights is rather limited. This article informs this gap using an original multi-level analysis of 126 peace agreements and three main categories of institutions involved in securing human rights implementation after conflictinternational and regional institutions for promoting and protecting rights, as well as national human rights ombudsmen and commissions. We find that peace agreements localise human rights implementation after the end of conflict, relying more on national human rights institutions than international ones to monitor and implement human rights domestically as well as advise governments on the ratification of international human rights treaties and assist national executives with processes of transition away from conflict and toward liberal democracy. While regional and international institutions like the United Nations and the Organisation for Security and Cooperation in Europe are included in some peace agreements, their roles are much more limited and nearly exclusively aimed at offering support to new and existing national human rights commissions. We illustrate our analysis with two case studies of peace agreements in Cambodia and Bosnia and Herzegovina.

This Element addresses questions of division of labor and concentration of authority among intergovernmental organizations by examining multilevel governance in the Global South. It focuses on the policy domains of peace and security and human rights in Africa and Latin America and the Caribbean (LAC), and its central finding is that the extent of governance regionalization varies across regions and issue areas. In the domain of peace and security, governance is most regionalized in Africa. In the domain of human rights protection, governance is most regionalized in the LAC region. Given the phenomenon of regional specialization, the Element makes the case for the greater explanatory power of regional drivers of regional institutional development. This Element is also available as Open Access on Cambridge Core.
