Lucia Stefanuto is a senior data analyst who loves getting ideas from Tableau Public to help improve her own dashboards and then shares that work to inspire others. She started her career studying business, marketing, and neuroscience, and has always been interested in discovering the “why” of things and how the mind works. She found analyzing data was a helpful path to achieve this and started processing data in Excel first. Once that data exploded, she tried other solutions before using Tableau, and it was love at first sight! Tableau increases her work efficiency as she processes, structures, and visually presents information in a clear, concise, actionable format. She prefers simple graphs that are easy to understand by non-data literates. Connect with Lucia on LinkedIn
