We'll be focusing on a dataset drawn from Wikipedia and [http://dbpedia.org DBpedia], containing the names, birth dates, genders, article creation dates, and number of edits, of over 180,000 Wikipedia biography articles. |

If matplotlib is install correcting, a chart file named '''histograms.pdf''' will appear in the current directory. |
