The Toolbox provides a window to the potential that data can provide for policy-makers and allows users to browse through its contents freely, using selected elements as inspiration for data use in policy, themselves. The backbone of the Toolbox is a series of case studies. These are structured narratives based on real-life examples of data supported policymaking. Each story contains links to related features in the Toolbox that support the story, for example, from the data used to the software tools, the visualisation created, and resulting policy elements. Visit the online Toolbox (https://policyvisuals.eu/) to read case studies that look into how the use of data visualisations assisted in making roads around schools safer, supporting people during COVID-19 lockdown, and using communication strategies to improve mobility and modal shift, amongst many others. The tool also provides detailed information for a list of 'Policy-Making Ingredients' which includes; Datasets Dataset Types Policy Elements Policy Processes Software Tools Techniques Visualisation Types The PoliVisu project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme.
