Mining Lending Club’s Goldmine of Loan Data Part I of II – Visualizations by State by Tanya Cashorali.
Very cool post that combines using R with analysis of a financial data set, plus visualization by state in the United States.
Of course the data has a uniform semantic so it really doesn’t present the issues that topic maps normally deal with. Or does it?
What if instead of loan data I had campaign contributions and the promised (but not delivered so far as I know) federal contract database? Which no doubt will have very different terminology as well as shadows and shell companies to conceal interested parties.
Developing your skills with R and visualization of mono-semantic data sets will stand you in good stead when you encounter more complex cases.
