This is a 2-hour online course providing an introduction to the process of data visualization. Data visualization is a process by which one can display data in a way that is relevant and interesting to an audience, as opposed to using traditional data reporting visuals.
[UPDATED SEPTEMBER 2015] Most of the time when we think about representing numbers in a visual way, we think about things like bar graphs and pie charts. These can be great tools for displaying development indicators, but recent software advancements have created a wealth of additional resources and tips for presenting data in ways that are both visually appealing and easy to understand. This field is called 'data visualization', and is loosely defined as the creation and study of the visual representation of data.
Those of us who work with data know that it is most useful when widely disseminated and shared with others – and this is where the popular emerging field of data visualization comes in. It focuses on creating data representations that are clear, attractive, and message-driven. Some big players have emerged in this field in recent years, including Edward Tufte, Stephanie Evergreen, Stephen Few, and Hans Rosling.
In this Trending Topic list we present some high-quality and easy to use tools to help you visualize your data, as well as some examples of how country projects have done this effectively. As you will see, there are many resources out there that will help get your creative data visualization juices flowing!
