Welcome to the world of accidental data lies, where innocent-looking charts quietly twist the truth. And in today’s world, where ethical data visualisation is a hot (and important) topic, it's something we all need to watch out for.

From spreadsheet wizards to Power BI spellcasters, this session will help you create visuals that don’t just dazzle, they tell the truth and earn trust.

We’ll explore the most common (and sneaky!) ways charts mislead, from pie chart pandemonium to axis trickery, colour chaos, and the dreaded “average of averages.” You’ll see real-world examples of chart crimes, laugh at some visual disasters, and sharpen your instincts for spotting visual deception.
