Visualising risk: a modern implementation of the Risk Characterisation Theatre

This post has originally been published on Medium by EDJNet A different visual approach to associate likelihood of occurrence of a given event to the lived experience of people viewing the graph. In their 2007 book “The illusion of certainty: Health Benefits and Risks”, authors Erik Rifkin and Edward Bouwer addressed a number of aspects related to the communication of risk to individuals and broad audiences, arguing that adequate communication of risk, including on the uncertainty embedded in risk assessments, is fundamental to personal and collective deliberations.

An online interface for associating latitude/longitude coordinates with administrative units

This post presents a data exploration tool developed by EDJNet. If you have a spreadsheet with longitude and latitude columns and would like to have a look at those data on a map or associate them with administrative units across Europe, you may well find this tool useful. You can try this online, or check out this screencast for an overview of its main features. The interface is available also through the R package latlon2map.

How do data grids look on a map? [3D video]

In this video, I point at some of the issues that characterise data grids and that may generate misunderstandings. In the video, I mention how gridded data can be generated via satellite imagery and machine learning techniques. Of course, such data can be generated also via other means. References This video is based on the data used for in this interactive web interface, presenting municipality-level data for most European countries:
