LA maps of crime: Using R to map criminal activity in LA since 2010

           · ·

I’ve recently come across — a huge resource for open data. At the time of writing, there are close to 17,000 freely available datasets stored there, including this one offered by the LAPD. Interestingly, this dataset includes almost 1.6M records of criminal activity occurring in LA since 2010 — all of them described according to a variety of measures (you can read about them here). Using information like the date and time of a crime, its location (longitude & latitude), and the type of crime committed (among other things), you can come up with some pretty interesting visualizations.
