To finish the data visualisation and communication course from the EPFL extension school, I needed to create something that would b e accepted as a capstone project. I decided to program another shiny app, again using open government data, like for the previous, smaller app. I came across the energy usage of the city of… Read More Energy use in Swiss cities – another shiny app

I am still working my way through the data visualisation and communication course from the EPFL extension school. Getting towards the end, I need to complete two projects, one of which certainly in the form of a golem-based shiny app (a shiny app is some interactive web app developed without too much web developing knowledge,… Read More How fast does help reach you (in Zurich)? A shiny app based on open government data

While it is alluring to declare that the pandemic is over – unfortunately, it’s an illusion. We’re deluding ourselves, delaying, and not using the time when cheap measures still have a lot of effect. From the perspective of being (mildly) affected with long covid, and hearing heartbreaking stories of other people who’ve got it much… Read More What I wish you knew about (long) covid

Yet another task in my course on Data visualisation and communication course from the EPFL extension school, which I already mentioned in my previous post, was to plot some data with a relation to geography. Could be a map with some extra features, could be choropleth map, could be a cartogram (Wikipedia has a nice… Read More More plots on women in parliaments

As part of the Data visualisation and communication course from the EPFL extension school, which I already mentioned in a previous post, one of the optional tasks after finishing the first of four sub-courses was to find timeseries data and plot it. A very open question! There is so much timeseries data – the vast… Read More Timeseries plot – Swiss residents

As I’ve started a course a couple of months ago on data visualisation, which is all in R, I’ve recently come across the R community’s #TidyTuesdays. If you haven’t worked with the programming language R, then you probably did not get the meaning of the last sentence – that’s fine, I was there not too… Read More Getting started with #TidyTuesdays

Recently I have been stretching my programming skills – mostly ith the course from the EPFL extension school called ‘Data Visualisation and Communication’, which is quite extensive when doing next to a full time job and covers all things visualisation in R. As I have done all my previous visualisations in python, this is all… Read More Learning something new is frustrating (but fun!)

Have you seen the climate stripes? These ones show the average global, yearly temperature deviation from the mean of the yearly temperatures between 1961 and 1990, from 1850 to 2020. In other words, you take some reference period (1961 to 1990) and check how different was each year from that reference period. Quite obviously it… Read More Hearing the climate stripes

This post is about and inspired by two books about what is happening in the age of the machine and big data, when algorithms wield control. One is ‘Weapons of math destruction’ by Cathy O’Neil, and the other one is ‘Hello world. How to be human in the Age of the Machine’ by Hannah Fry.… Read More How to be human in the age of the machine

Also, stolz ist man ja nicht auf dieses erst fünzigjährige Jubiläum. Gar nicht. Syrien, die Philippinen, Moldau, Burundi, Senegal, Venezuela, Spanien, Eritrea, China, Togo, und ganz viele andere Länder haben das Frauenstimmrecht vor der Schweiz eingeführt. Vielleicht müsste man die kleinere Zahl nennen – wieviele Länder das erst nach der Schweiz eingeführt haben. Und überall… Read More Lesestoff zum Jubiläum des Frauenstimmrechts
