During the EGU General Assembly 2025 in Vienna, the short course “DataViz: Visualise your data effectively and avoid common pitfalls” was once again delivered by the Young Hydrologic Society (YHS). Now a well-established tradition at EGU, this course is designed to equip early-career scientists (and anyone interested) with both inspiration and practical tools to enhance their data visualization skills. In a time when visuals often speak louder and travel faster than words, the ability to create clear, accessible, and visually compelling graphics has become an essential part of scientific communication!
