Modelling 🦠 Coronavirus – Quarantine?!

As coronavirus is threatening to become a global pandemic, I’ve built seven epidemiological models of increasing complexity in order to illustrate how infectious diseases get transmitted over time. Among others, I try to answer the questions of what is the scientific rationale behind a surgical mask or an all-out quarantine. This is a video commentaryContinue reading “Modelling 🦠 Coronavirus – Quarantine?!”

Metrocyclopaedia 🚇 Interactive map of all metro systems of the world

I have been playing around quite a bit with CesiumJS recently. It is likely the best tool out there to visualize global datasets on an interactive 3D Earth in the browser. As you might know from the title of his blog, 😁 I am fascinated by complex systems. A particular kind of complex systems areContinue reading “Metrocyclopaedia 🚇 Interactive map of all metro systems of the world”

D3 liquid fill gauge for maps

I teach a data visualization course, and recently one of my students has come to me with the idea of “half-filling map areas”. I was like that’s a great idea, go find an example on the internet, I’m sure there is plenty. Well, as it turns out, there isn’t plenty, so I’ve decided to doContinue reading “D3 liquid fill gauge for maps”
