7 Reasons You Should Use Dot Graphs, by Maarten Lambrechts

7 Reasons You Should Use Dot Graphs, by Maarten Lambrechts

In my data visualization courses, I often refer to the hierarchy of visual encoding proposed by Cleveland and McGill. In their 1984 paper, Cleveland and McGill proposed the table below, demonstrating to what extent different visual encodings of data allow readers of data visualizations to accurately assess differences between data values. DOI: 10.2307/2288400 Since then, … Continue reading 7 Reasons You Should Use Dot Graphs, by Maarten Lambrechts

Making GIFs with Processing

Making GIFs with Processing

Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. It's open-source, there are many online materials, and the language itself is very accessible. I recently stumbled upon 17-year-old Joseff Nic from Cardiff who has been making GIFs in Processing only since 2018, but … Continue reading Making GIFs with Processing

ROC, AUC, precision, and recall visually explained

A receiver operating characteristic (ROC) curve displays how well a model can classify binary outcomes. An ROC curve is generated by plotting the false positive rate of a model against its true positive rate, for each possible cutoff value. Often, the area under the curve (AUC) is calculated and used as a metric showing how well … Continue reading ROC, AUC, precision, and recall visually explained

Animated Snow in R, 2.0: gganimate API update

Last year, inspired by a tweet from Ilya Kashnitsky, I wrote a snow animation which you can read all about here.  Now, this year, the old code no longer worked due to an update to the gganimate API. Hence, I was about to only refactor the code, but decided to give the whole thing a minor update. Below, … Continue reading Animated Snow in R, 2.0: gganimate API update

Animated vs. Static Data Visualizations

Animated vs. Static Data Visualizations

GIFs or animations are rising quickly in the data visualization world (see for instance here). However, in my personal experience, they are not as widely used in business settings. You might even say animations are frowned by, for instance, LinkedIn, which removed the option to even post GIFs on their platform! Nevertheless, animations can be … Continue reading Animated vs. Static Data Visualizations
