Open Data (OD) is one of the most active movements contributing to the spread of information over
the web. However, there is no common standard to publish datasets. Data is made available by
different kind of entities (private and public), in various formats and according to different cost models.
Even if the information is accessible, it does not mean it can be reused. Before being able to use it, an
aspiring user must have knowledge about its structure, location of meaningful fields and other
variables. Information visualization can help the user to understand the structure of OD datasets.
