Palindromic place names in Switzerland 🇨🇭 Of the over 35,000 official place names in the #swissNAMES3D dataset, (only) 13 are palindromes. Idea by @dgplacenames, found at @_ansgar Data: geo.admin.ch Created in #rstats

Christmas spirit sprinkled with a little bit of 8-bit, a large portion of #tidyverse, spiced up with some ffmpeg magic and voilà: 🎄#rstats

Seit nun 7 Wochen läuft die #Migros-Förderaktion «Support your Sport», bei der Schweizer Sportvereine durch das Sammeln von Vereinsbons an CHF 3 Mio. partizipieren können. Wir haben die neuesten Zahlen angeschaut und wagen eine erste kleine Hochrechnung. gfzb.ch/data/migros-sp…


Playing around with the fantastic and free geodata from @swiss_geoportal Spatial kernel smoothing of ~40k geo-ref'd place names. BTW, {swissgd} an #rstats wrapper around the services is now ready to be tested: ➡️ github.com/zumbov2/swissgd @swisstopo @opendataswiss @OpendataCH

Do Switzerland's staggered ⛷ vacations qualify as a natural experiment to investigate the effect of school closures on the spread of #COVID19? Asking for a friend. 😉@marcelsalathe @C_Althaus @SwissScience_TF

A positive impact of 2020? Our @giourugg picks👇 Flaws of choropleth maps were in the spotlight after US elections, as "land doesn't vote, people do". Visual explainer of perception distortion when used on raw data: twitter.com/DavidZumbach/s… #dataviz #learningwithexts

Don't trust choropleth maps. Evidence from Switzerland! 😉 #RStats   Shout-outs to @thomasp85 for {transformr}/{particles}, @hadleywickham et al. for {ggplot2}/{dplyr}, @edzerpebesma for {sf}, @politan_ch for {swissdd} and @hrbrmstr for {hrbrthemes}.   ➡️ github.com/zumbov2/votema…

I couldn't agree more. Beautifully executed demonstration of how choropleth maps can lead to wrong interpretations.
