Data Storytelling

Presenting analysis so the insight and recommended action are unmistakable, not just the numbers.

What it is

Data storytelling is the practice of presenting analysis so that the insight and its implication are unmistakable — the difference between a chart someone has to interpret and one that makes its point immediately.

Key points

  • Lead with the insight, not the data: "revenue is at risk in the EU region" is a stronger opening than a chart with no framing that requires the audience to derive that conclusion themselves.
  • One chart, one point: a chart trying to show too many series or comparisons at once usually ends up communicating none of them clearly — narrowing scope makes the message land.
  • Context makes numbers meaningful: "$2M in revenue" means little without context — versus target, versus last quarter, versus the industry — the comparison is what turns a number into an insight.
  • The goal of data storytelling is a specific decision or action from the audience — analysis that doesn't lead anywhere actionable, however rigorous, often fails to actually change what happens next.
