Europe by Numbers: Data for Stories

Hi everyone,

Here’s my entry for the Power BI DataViz Championship EU Edition.

The report focuses on two key goals:

  1. Providing quick and accessible insights for journalists to help them kick-start their writing process.

  2. Allowing a deeper dive into the data for more detailed exploration.

The report consists of five pages:

  • Home Page – A brief overview that gives a glimpse of what to expect.

  • Insight Page – A tool for journalists to quickly find insights across different datasets and regions. By applying just a few filters, journalists get a list of scenarios with dynamic key insights and visuals. I also included a sentiment filter that lets them choose the angle they want to write from (positive, negative, or neutral).

  • Population Page – A deeper dive into population data, showing how growth has developed over time.

  • Culture Participation Page – Insights into who is most active in cultural activities.

  • Happiness Page – More detailed information on life satisfaction scores.

The design is centered around the needs of journalists. For example, the Insight Page uses a two-column layout:

  1. Parameter selection (topic and region).

  2. Automatically generated visualizations — essentially a “first draft” for an article, with a suggested title and key insights.


The other report pages all follow a consistent design for ease of use, with:

  1. Slicers to filter the data.

  2. Dynamic insights that summarize key European averages (with expandable/collapsible details for a cleaner look).

  3. Map visuals to highlight country-level differences.

  4. A side panel with three visuals: one for regional comparisons, one for trends over time, and one table showing highest/lowest values to help uncover story ideas.


Small design details
that might go unnoticed but add value:

  • Dynamic data labels in line charts (highlighting only the selected year).

  • Animated icons for a more interactive feel.

  • Customized data labels for map visuals.

  • Alt text and an accessibility-focused color scheme.

If you have any feedback, I’d love to hear it. And if you like the report, a like would mean a lot!
