Abstract

<p>Electrical Japan is the website that collects, integrates, and visualizes electricity data centered on Japan, and plays a role on constructing long-term and comprehensive database through the preservation of otherwise disappearing data. We first classify visualization approaches into three types, namely visualization for comprehension, visualization for attraction, and visualization for insight, and claim that Electrical Japan aims at visualization for insight, thereby realizing situational awareness and data journalism. We then introduce case studies of visualization, such as electricity usage, power plant maps, and electricity statistics visualization, together with important design consideration. Finally, we explain the workflow starting from data collection to integration and visualization, and discuss relevant issues about the release of public data.</p>
