Storytelling with Data (book and blog)

What it is

Storytelling with Data (SWD) began as a book by Cole Nussbaumer Knaflic, published by Wiley in 2015, drawing on her work in Google's People Analytics team. It has grown into a site with a free blog, a podcast, a community and monthly challenges where people remake a chart on a set theme. The author's published bio says the book has been translated into a dozen languages and is used as a textbook by more than 100 universities.

What you learn

The core lessons are simple and they change how your work lands:

• Understand the context first: who is the audience, what do you want them to know or do, and what is the one-sentence point.
• Choose an effective visual. For most business data that means a simple bar or line chart, not a pie, a 3D chart or a gauge.
• Remove clutter: borders, gridlines, redundant labels and legends that make people work.
• Focus attention with colour and position, so the viewer sees your point first.
• Think like a designer, then tell a story with a beginning, middle and end.

Each idea comes with before and after examples, which is why it sticks.

Is it worth your time?

Yes, for every analyst. Many analysts can build a dashboard; far fewer can make a manager understand it in thirty seconds. That second skill is what gets your work used. Start with the free blog posts and the challenges, then read the book when you begin presenting results.

Free vs paid

The blog, podcast, community and challenges are free on storytellingwithdata.com. The books are paid, and there is also a follow-up workbook (Storytelling with Data: Let's Practice!) with exercises. Many libraries stock the original book.

How to use it

Take a chart you made recently and apply the chapters one by one: rewrite the title as the takeaway, strip the clutter, use one highlight colour, and ask a friend what they notice first. Do this for every portfolio project.

Common questions

Is it tool specific? No. The examples are mostly made in Excel, and the principles apply equally to Power BI, Tableau and Python.

Is it only for presentations? No. The same ideas make dashboards and written reports clearer.
