Data visualisation is crucial in presentations as it simplifies complex information, captivates and maintains audience attention, and helps decision-makers see the big picture.
To do data visualisation right, it is important to know the audience, choose the right visual for the data, keep it clean and simple, use color thoughtfully, provide context with labels and annotations, and test the visuals before the presentation.
Common pitfalls to avoid include misleading visuals, overuse of pie charts, overcrowded slides, and ignoring accessibility.
Data visualisation transforms numbers into insights, keeps the audience engaged, and empowers decision-makers by telling a compelling story.
