A Quick How-to on Labelling Bar Graphs in ggplot2

Bar charts are likely the most common chart type out there and come in several varieties. Most notably, Direct labels can increase accessibility of a bar graph. I got a request how one can add percentage labels inside the bars and how to highlight specific bars with {ggplot2}. This short tutorial shows you multiple ways how to do so.

Visualizing Distributions with Raincloud Plots (and How to Create Them with ggplot2)

Raincloud plots, that provide an overview of the raw data, its distribution, and important statistical properties, are a good alternative to classical boxplots. In this tutorial, I highlight the potential problem of boxplots, illustrate why raincloud plots are great, and show numerous ways how to create such hybrid charts in R with {ggplot2}.

My Contributions to the First 30DayChartChallenge

This April, Dominic Royé and I hosted the first #30DayChartChallenge, a data visualization challenge with the aim to create a chart every day of April with a given prompt. In total, we collected 1,960 contributions from around the world!

My Personal Data Visualization Year 2020

Even though it was a crazy and exhausting year, there were also some good and exiting things happening. Therefore I've decided to take a short break on New Year's Day and look back at some of the positive moments of my personal data visualization journey during 2020.

What do I binge next? A detailed overview of the top 250 TV shows

My contribution to the RStudio table contests visualizing relevant details of the top 250 TV shows as rated by IMDb users. I focused on displaying all the details I and my friends care about including in-line visualizations of rating trends and average runtime.

The Worst Days of the Coronavirus Pandemic So Far

Coronavirus SARS-CoV-2, COVID-19 or simply Corona—what started as an epidemic in China’ has become a global pandemic. I created an animated timeseries of daily deaths relative to each country's worst day so far to visualize the first wave of COVID-19.
