A chart that nobody understands in three seconds has already failed, no matter how accurate the underlying data is. The Arab British Fellowship Training Academy designed this Data Visualization course around that reality, training participants to turn raw numbers into visuals that stakeholders actually read, trust, and act on.

The course moves from design fundamentals — visual hierarchy, color theory, and data storytelling — into hands-on work with Excel, Tableau, and Power BI, covering everything from basic bar and line charts to interactive dashboards, geographic visualizations, and dynamic animations. Data cleaning and preparation get dedicated attention, since no visualization is better than the data behind it, and the course closes with the ethical side of the craft: accuracy, transparency, and how to avoid charts that mislead even unintentionally. Participants leave able to choose the right visual for any dataset and present it with confidence.

Who Should Attend?

• Business analysts working to improve data communication.
• Data scientists building understandable visuals from large datasets.
• Marketing and sales professionals presenting metrics and trends graphically.
