Hello there and welcome!

My name is Christian and I have a passion for clear and appealing data visualizations.



Have a look at my previous visualizations and ongoing projects. If you want to talk about communicating your data or if you’re looking for a data visualization training, feel free to contact me.

SPACE AHEAD: Setting and Audience

At the beginn of “SPACE AHEAD” you should actively consider how, where and to whom you present your data. Let’s take a look at why this matters and why slapping your figure from a paper onto a presentation slide might not be the best approach.

AI generated image using Midjourney with the prompt: 'An adventurous astronaut in a space suit, seen from the back with a light angle. He is pointing his finger, as if he was pointing to a distant aim, where he aspires to go. In the background there are stars, planets and a few distant galaxies. The style should be a retrowave, synthwave album cover.'

Mind your SPACE AHEAD

Visualizing scientific data in a clear and compelling way can be hard, as the underlying matter is complex and time often is short. The “SPACE AHEAD” acronym helps conceptualise the desired chart and gives pointers on where/how to optimise the design and accessibility. This first part of the series can be used as a go-to checklist, when you’re not happy with the default settings of your software and don’t know where to start. I’ll dive into more details in the following posts.

Ten scrabble letters spelling the words 'Order' in the top and 'Chaos' in the lowe part. The letters forming 'Order' are nicely arranged, while the letter spelling 'Chaos' are arranged in a chaotic way.

Cleaning Babynames

In this post I download, clean and tidy open data from the City of Munich regarding baby names. The available datasets have different filename patterns, column names, delimiters, typos and implicitly missing data. I’ll use the cleaned data for future posts.

Export plots in WebP format

Since there’s no “built in” way to export R graphs to WebP images, {webpea} offers a function to save single plots or to automate WebP export in quarto / Rmd documents.

An image of a small wooden table with a flower on it. To the left and right are empty chairs. The scene is set in front of a white painted brick wall, which fills the whole background.

Integrating tables in plots

Including a table in a graph can be very informative. Unfortunatley that wasn’t very straight forward in {ggplot2} - until now. I revisit one of my plots for #30DayChartChallenge to showcase how to include a {flextable} into a plot using {patchwork}.
