This application was inspired by the
Worldwide clustering of the corruption perception
We used the
Transparency International's Corruption Perception Index
for the report years 2014, 2013 and 2012.
To build the fan-style dendrogram we have used a hierarchical clustering algorithm with different agglomerative methods. Our cluster is based upon the euclidean
distance of each country's CPI observation. We can also filter the dataset based on the region and cut the tree so that clusters having the same height share
the same color.
