Course Objective & Scope

Cluttered charts, misleading axes and dashboards without a clear message can turn even correct data into wrong decisions. The programme covers tool-independent principles such as chart selection, pre-attentive attributes, colour palettes, the data-ink ratio and accessible design.

Participants redesign sample reports taken from the organisation, build a data storytelling flow and finish with a visualization checklist the team can reuse. Exercises run in Power BI, Tableau or Excel, depending on the tool the organisation uses.
