Can I create a word cloud of crowdfunding donors using word cloud?
I will give you a simple solution using R which requires the wordcloud package. Of course there are many other solutions which do not require any programming skills.

The solution is a slight varient of this R-Bloggers tutorial. Feel free to have a look there for further formatting.

library(wordcloud)

words = c('Paolo Gentiloni', 'Matteo Renzi', 
          'Enrico Letta', 'Mario Monti', 
          'Silvio Berlusconi', 'Romano Prodi')
freq = c(100, 25, 50, 70, 95, 20)

wordcloud(words = words, freq = freq, min.freq = 1,
          max.words=200, random.order=FALSE, rot.per=0.35, 
          colors=brewer.pal(8, "Dark2"))


It produces the following output:


Btw. @Lorenzo Perone: Where the ones listed Italien names? I was not sure about that.
