When sharing data online, three aspects deserve particular attention, as Shannon and Weaver explained in their seminal article “The Mathematical Theory of Communication” (1949), these are:
- Technical: accuracy of transmission
- Semantic: precision in transferring the meaning
- Effectiveness: impact on conduct
According to Jones (2014), effective data communication is based on six main principles):
- Know your goal: your audience, desired effect, intended meaning will guide your message.
- Use the Right Data: select a proper amount of data, ensuring ethical and reliable messages.
- Select suitable visualizations: use graphical representations to translate your data.
- Design for Aesthetics: engage your audience with attractive data visualizations (e.g. colours, fonts, labels, images).
- Choose an Effective Medium and Channel: the form and way of delivery of the message influence its impact on the audience.
- Check the results: be careful of reach (did the audience receive the message?), understanding (was it interpreted in the right way?), impact (Was the reaction the same you expected?) (Reilly, 2014).
Visualizations can facilitate the meaning of data, bringing it “alive”, increasing its 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).
