1955, Chilean socialist intellectual Oscar Waiss visited Yugoslavia together with senator Aniceto Rodríguez. Waiss impressions and thoughts are to be found in his book Amanecer en Belgrado. Here’s a link to an interactive map made with R using the Leaflet library and showing the sites and impressions that Waiss got during his tour around Yugoslavia. The map allows user to compare his tour with the one that Chilean socialist leader Raúl Ampuero carried out in the country two years later.
Thanks to my friend Giovanni Pietro Vitali for suggesting a very efficient workflow to code this map.
