Power BI report ´Big 3 of Tennis´with qualitative data and the Power BI custom visual Card Browser

 #93 Power BI report ´Big 3 of Tennis´ with qualitative data and the Power BI custom visual Card Browser

The other day, a friend asked me if I could help with a dashboard for his work that should facilitate data-exploration of the results of a survey which had just qualitative data. So the dashboard was not supposed to be the typical ´pivot-table dashboard´ with measures (e.g. sales) and some dimensions (e.g. Product, Customer, Date), but more a ´Power Point interactive dashboard´.

I checked on the web if there were examples of Power BI dashboards with qualitative data, and found this:

https://community.fabric.microsoft.com/t5/Data-Stories-Gallery/Productivity-Hacks-Transforming-Text-using-Power-BI/m-p/1429945

This dashboard is made by DiscoverEI , that converted a 107 pages (e-)book into an interactive Power BI report. As they say: 

"Power BI is not just limited to visualising quantitative data, it is also a fantastic data storytelling tool for transforming large amounts of text (qualitative data) into an interactive dashboard"

Another intersting example of this, is the (public) dashboard they made for the project ´Environmental Data Storytelling - Gippsland Water's Urban Water Strategy´:

In their dashboard, I saw the Card Browser Power BI custom visual which I thought could be interesting to use into the prototype dashboard for my friend. 

First I created with ChatGPT the dataset for my report, so with some properties of the ´Big 3 of Tennis´, Federer, Nadal and Djokovic, e.g. favourite surface (clay, grass, hardcourt), left/right handed, playing-style (baseline, all court) etc. Then I made the Power BI report for this data, so using the Card Browser visual:



And in animated gif format:



NB: the data of this report is correct for Federer (retired in 2022) and Nadal (retired in 2024), but a bit outdated for Djokovic, who is still active and has now (Sept. 2025) 100 ATP titles, making hem part of the group of 3 tennis players with 100(+) ATP-titles, with Federer (103 titles) and Conners (109 titles)

And for a (longer) video with a demo of this dashboard, see:

NB: at the end of my video, there is a fragment of the match:

Rafael Nadal vs Roger Federer - Battle of Surfaces 2007, an exhibition match where half of the court was of clay (the favourite surface of Nadal) and the other half was of grass (the favourite surface of Federer) , source:

In my Power BI report I also added a page that shows a more normal use of Power BI :)


On the web, you can find discussions on who´s the real GOAT of tennis, e.g. :

and for the ones who like Nadal best, you might like this other post that I made after Nadal retired:

To conclude, here are 2 more nice examples of ´Power Point dashboards´ (Power BI reports) with qualitative data, made by Ecorys:

https://poseidon.safe-europe.eu/dashboard - Dashboard with anti-corruption practices in the EU seaports supply chain 

https://fightagainstcorruption.eu/Dashboard - Dashboard with anti-aorruption practices in the EU, as described in ´Handbook of good practices in the fight against corruption´.

For these dashboards, a lot of attention was paid to the design of the user interface, and in this video of Greg Deckler, you can learn more about the UX-design work for a Power BI report, for which he uses in this very nice dashboard:

NB: Deckler participates with this dashboard in The Power BI DataViz World Championships 2025, and on this Fabric/Power BI Community page, you can find work of other participants of the FabCon event, like:
