A good chart tells a story; a bad one hides it. When dashboards guide strategy, clear visuals become essential.

Here are practical tips for turning raw numbers into insights that leaders can act on.

A well-designed chart is a decision waiting to happen.

Choose the right chart

Line charts for trends, bar charts for comparisons, scatter plots for correlations: match the chart to the question.

Simplify colour and labels

Use a muted palette and highlight only what matters. Avoid 3D effects, which distort perception.

Provide context

Benchmarks and targets give numbers meaning. Without them, numbers float in a vacuum.

Good visualisation bridges data and decisions. The right chart at the right moment can change a business’s direction.
