In recent years many government organizations have imple- mented Open Government Data (OGD) policies to make their data publicly available. This data usually covers a broad set of domains, from financial to ecological informa- tion. While these initiatives often report anecdotal success regarding improved efficiency and governmental savings, the potential applications of OGD remain a largely uncharted territory. In this paper, we claim that there is an important portion of the population who could benefit from the use of OGD, but who cannot do so because they cannot perform the essential operations needed to collect, process, merge, and make sense of the data. The reasons behind these prob- lems are multiple, the most critical one being a fundamental lack of expertise and technical knowledge. We propose the use of visualizations as a way to alleviate this situation. Vi- sualizations provide a simple mechanism to understand and communicate large amounts of data. We also show evidence that there is a need for exploratory mechanisms to navigate the data and metadata in these visualizations. Finally, we provide a discussion on a set of features that tools should have in order to facilitate the creation of visualizations by users. We briefly present the implementation of these features in a new tool prototype focused on simplifying the creation of visualization based on Open Data.
