Here’s a useful resource for anyone involved in data journalism and visualising the results. ‘Dataviz‘ – a site for “improving data visualisation in the public sector” – features a step by step guide to good visualisation, as well as case studies and articles.
Although it’s aimed at public sector workers, the themes in the former provide a good starting point for journalists: “What do we need to do?”; “How do we do it?” and “How did we do?” Each provides a potential story angle. Clicking through those themes takes you through some of the questions to ask of the data, taking you to a gallery of visualisation possibilities. Even if you never get that far, it’s a good way to narrow the question you’re asking – or find other questions that might result in interesting stories and insights.
