Data Storytelling for Slides

Turn raw data into compelling visual narratives that audiences understand, remember, and act on.

Core Principles

1. Data Without Story Is Just Numbers

A chart without context is meaningless. Every data point should serve a narrative: "Revenue grew 40% because we launched the mobile app" is a story. "Revenue was $1.2M" is just a number.

2. Show the Relationship, Not Just the Data

The best data slides reveal relationships: cause and effect, before and after, actual vs. target, you vs. competition. Comparison is the foundation of insight.

3. Maximize the Data-Ink Ratio

Remove anything in a chart that isn't data or essential context. Gridlines, borders, 3D effects, excessive labels — eliminate noise. Every pixel should either inform or guide.

4. The Audience Should Arrive at the Insight in 5 Seconds

If a viewer can't understand the key takeaway within 5 seconds, the visualization has failed. Pre-attentive attributes (color, size, position) should make the insight immediately obvious.
