|When sharing data online, three aspects deserve particular attention, as Shannon and Weaver explained in their seminal article “The Mathematical Theory of Communication” (1949):
Effective data communication is based on six main principles (Jones, B., 2014):
Visualizations can facilitate the meaning of data, making them “alive”, increasing their persuasiveness and highlighting trends, connections, patterns (Verghese). According to the Harvard Business Review, visualizations should always: be tailored for the audience, provide a common reference for interpretation, convey a story. Making an emotional connection to your audience is a sign of proper use of data visualizations (Zandan).
Open data commons offer legal tools and licenses to support the publication, provision and use of open data. Another well-known option is Creative Commons (CC) licenses: they offer a strong legal code made of a short summary and a machine-readable code, with different kinds of authorisations and limits on re-use. Generally, CC0 license is advised to make a resource effectively “open”.
