A short while ago I received the following request via Twitter:
Recently Matt published his own stab at the visualization and a link to the data-files on his blog:
Today I would like to present the dataviz that I would use to represent this kind of data. The technology I use is Qlik Sense with the Dependency Wheel extension*. The locations where the embassies are located are stored in a drillable dimension: continent, country, city. The width of the bands is determined by the number of cities in the respective continents and countries.
When you click on Belgium, Africa and on Congo, the graph adapts dynamically to these selections as follows in the order of the clicks.
- The dependency wheel extension is an open source add-on to Qlik Sense made available by Ralf Becher. It can be downloaded for free from GitHub.
