Data Visualisation Best Practices
Effective charts make decisions easy. In presentations, a chart's job is to prove a single point quickly. Follow these rules to make your data work for you, not against you.
Choose the right chart
Bar charts compare categories. Line charts show trends. Scatter plots reveal correlations. Tables are for exact values; use them sparingly in slides.
Highlight the single metric
Annotate the key number and make it visually dominant, a coloured callout or large bold label, so your audience immediately understands the takeaway.
Simplify axes and labels
Remove unnecessary gridlines and tick marks. Shorten axis labels and use consistent units. If the audience needs detail, provide a downloadable appendix, not a crowded slide.
Design Better, Faster

Arrange charts in a narrative sequence: context → trend → implication → recommendation. Each visual should answer one question that moves the story forward.
Conclusion
Good visualisation is ruthless editing. Remove distractions, emphasise the insight, and make the action obvious. When in doubt, simplify.
