Usually US economic pain is cushioned by falling bond yields and a strengthening dollar, which mean lower interest rates and more spending power for consumers.

This time we’re seeing the opposite, meaning the pain will be amplified.

Topic: Timeseries / Urbanization

Big question: how to explain the 'world'? Small multiples are a powerful way of providing an overview of important developments over time, while still providing the opp to delve into detail if required.

Horizon charts are great for showing multiple time series in a limited amount of space. Sometimes, you really don’t have much room but still want to show the density or intensity of events over time.

Relationship / negative

Can a negative relationship be positive? I thought about Hans Rosling for inspiration and came up with this dataset. I've never seen such a strong correlation (the y-scale is logarithmic) in data I work with.

I felt overwhelmed by this one, not being able to find a good dataset. I decided to use a dummy set and simulate sth, without having a specific question in mind. Perfect conditions to fail 🤣 ... here is my input 👾

Day nine of the #30DayChartChallenge 2025 theme: Distributions / Divergence What is Healthy Life Expectancy (HALE)? It is the number of years a person can expect to live in good health, without serious illness or disability.

It's one of the most important indicators of quality of life. It's not just about living, it's about living well.

Here are data from 2021 (WHO) on HALE in different continents.

Today it's about the most famous non-prof cycling event in core Europe - the Ötztaler Radmarathon. 220 km ride and 5.500 meter of ascent. I took the 2024 result of the general class for men and women. I wish I could do that on my own one day ...

Day eight of the #30DayChartChallenge 2025

Theme: Distributions/Histogram

Continuous data are for histograms. Helps to reveal skewness, central tendency or outliers. This makes them particularly useful for understanding the shape and spread of data sets at a glance.

Day seven of the #30DayChartChallenge 2025

Topic: Distribution / Outliers


A key goal of data visualisation is always to identify patterns. And patterns become visible when they are broken: Outliers. Then you can see, for example, that something is really not working.



#PowerBI #DENEB

A chart with four circular plots shows how people aged 10 and older in Germany spend their day, based on percent of people engaged in each activity by time of day. The four categories are: Sleep/personal hygiene (peaking between 22:00 and 07:00), Work/education (highest from 08:00 to 16:00), Eating (small peaks around 08:00, 13:00, and 19:00), and Leisure (most common between 16:00 and 22:00). Eating is spread throughout the day with peaks at traditional meal times.

How Hans Mustermann and Gabi Musterfrau spend their day.

Averages from the German Time Utilisation Survey 2022.

Some shared preferences for eating times, it appears.

Big numbers are hard to relate to. How much is a billion fortune? My question for today was, how can we explain this amount in a meaningful way? So I took Heath/Starr's "Making Numbers Count" approach. 😅

Topic: Comparisons/Fractions 

I've always been amazed by this kind of competition over the past few years and a few days ago I thought, this year I definitely need to get my entries in. 

As I mainly work with Power BI in my job, I'm still wondering if I can stick with it or if I need to switch to RSTATS, which I really love but still lack a broader experience with. But I know that with the topic "Uncertainties" Power BI might be reaching its limits. Let's see how it goes. 

Today I provide map tiles for some European countries, showing minimum wages in a Euro bill symbol, filled as related to the highest minimum wage in Europe Luxembourg (100%). Some countries have no minimum wage like Austria and Switzerland.

I took the D3.js visual from the marketplace for its implementation.

Power BI with web technology? 🥳

The development of UI on the web has made great progress. As users, we quickly get used to it and only realise when sth is missing.

The D3.js visual is a possibility to catch up..

Here is onee with highlighting effect when moving the mouse over it

Power BI offers some nice possibilities with custom visuals. I recently had the chance to play around with the D3.js visual from the Marketplace. This visual runs on Version 3 (Version 7 is current).
