Discovering the power of data visualisation: A recap of our October webinar series

Over three insightful sessions from 14-16 October 2025, the data.europa academy hosted the “Visualising Data for Impact” training series, led by renowned data visualisation expert Alberto Cairo. The series aimed to provide participants with the skills to transform complex datasets into clear, ethical, and engaging visuals. Each 90-minute episode blended theory, practical examples, and curated resources, attracting a diverse audience from public, private, and academic audiences. 

The first episode, Foundations of Effective Data Visualisation, introduced the principles of information design and debunked common myths such as “the data should speak for itself.” Participants explored the grammar of graphics and learned how to make deliberate, audience-centred design choices. The second session, Designing with Integrity, tackled the ethical dimensions of visualisation, highlighting how poor design can mislead and offering strategies to avoid distortion. The final session, Data Storytelling and Creating Your Narrative, focused on structuring layouts, building compelling narratives, and using creative design to enhance message clarity.  

This training series strongly aligns with the mission of open data to make information accessible, understandable, and actionable. By mastering visualisation techniques, data practitioners can unlock the full potential of open datasets, enabling better decision-making, transparency, and public engagement.
