All roads lead to Rome?

Well, here’s a map to check that saying.

The Cologne “Grüngürtel” (Green Belts) emerged from former fortress areas. Mayor Konrad Adenauer recognized the importance of a natural air filter for the people in the city. The Inner Green Belt and the Outer Green Belt were built between 1922 and 1924.

Zur Bekanntheit - das ZDF veröffentlicht m.W. die Bekanntheitswerte nicht. Daher ARD Deutschlandtrend von 09/25: 51 % geben an, Reichinnek zu kennen. Allerdings auch nur 63 bzw. 64 % Bas und Wadephul. Beim ZDF werden die Politiker:innen ungestützt erfragt, d.h. die Befragten nennen bis zu 10 Namen.

How long does it take your kid to get to their secondary school in Cologne?

It depends on where you (and your child) live and what type of secondary school your child attends. (Path times to the nearest school by bike.)

#30DayMapChallenge | Day 03 - Polygons #rstats #ggplot2
A map which shows the path times by bike to the nearest school for 4 secondary school types from each point within Cologne: Gymnasium (academic secondary school), Gesamtschule (comprehensive school), Realschule (intermediate secondary school), Hauptschule (secondary general school). The academic secondary schools are found closer to the city center compared to other school types.

Heading to Vienna tomorrow for the #IEEEVIS 2025 conference.

Time to get familiar with the city’s public transport network. 😅

I’ve marked the conference venue, the Austria Center Vienna, on the map.

A map which shows the public transport network as minimalistic black lines on a light background. The area is limited to a circle. The location of the Austria Center Vienna is marked with a dot in the Northeast of the map.

Leider null Lernfähigkeit beim ZDF. Obwohl die Redaktion einen halben Tag Zeit zur Korrektur gehabt hätte, entscheidet sie sich, das irreführende Diagramm im TV zu präsentieren.

So show your #worldfootballR charts! 📊⚽️

That transfer season when Chelsea spent more than 600 million EUR on new players to secure the 12th place in the final Premier League table.

#dataviz
2 treemaps showing the investments of football clubs in the top 5 European football leagues (Premier League, LaLiga, Bundesliga, Serie A, Ligue 1) in the summer and winter transfer windows 2022-23. The amount spent on player transfers by each club is represented by a proportionally sized rectangle. Clubs are nested within leagues in the treemap. Premier League clubs are highlighted, and within these, Chelsea is highlighted.

I'm starting with this which I created for the #30DayChartChallenge this year.

#dataviz
Scatterplot showing LaLiga strikers' efficiency in the 2024-25 season by comparing expected non-penalty goals (x-axis) with actual non-penalty goals per 90 minutes (y-axis). Players above the diagonal line are outperforming their expected goals. Notable overperformers include Ayoze Pérez, Alexander Sørloth, and Robert Lewandowski, while Kylian Mbappé, Vinicius Júnior, and Lamine Yamal are closer to or below expectations. Bubble sizes indicate total goals scored.

Wir hatten das 9-Euro-Ticket, nun soll das Deutschlandticket künftig 63 EUR kosten.

Musste an Ivan Zamorano denken:

Sentence from the article in the quoted post: "In fact, the Israeli military officials said, the U.N. aid delivery system, which Israel derided and undermined, was largely effective in providing food to Gaza’s desperate and hungry population."

Im Mai wurde ein Verfahren gegen Kardinal Woelki wegen Meineids im Zusammenhang mit Missbrauchsfällen im Kölner Erzbistum gegen die Zahlung einer Geldauflage eingestellt.

Die 26.000 EUR dürfen laut Staatsanwaltschaft nicht an eine kirchliche Einrichtung fließen. 🙏
26.000 Euro für gemeinnützigen Zweck Die Geldauflage von 26.000 Euro entspricht laut Erzbistum zwei Monatsgehältern des Kardinals. Das Geld soll an eine gemeinnützige Organisation fließen – ausdrücklich keine kirchliche Einrichtung, wie die Staatsanwaltschaft betont.
