Visualising Crime

New York Daily Gun Deaths. Each bullet represents a death. Colors show the type of death i.e. suicide, homicide, accidental or legal police action. Counts are broken down by age group.

For almost every reported crime, there’s a paper or digital record of it somewhere, which means hundreds of thousands of data points – number of thefts, break-ins, assaults, and homicides as well as where and when the incidents occurred. The NYPD (and more recently, the LAPD) use COMPSTAT, an accountability management system driven by data.While a lot of this crime data is kept confidential to respect people’s privacy, there’s still plenty of publicly available records.

Visualising the 9/11 terrorist network

prefuse - 9/11 Terrorist Network Author(s): Jeffrey Heer, Alan Newberger

These images visualise suspected connections between terrorists involved in the September 11th attacks. The width of the line indicates how strong the suspected link is. People are placed on concentric circles based on the number of links between them and the central person, making it easy to measure the social distance between the central person and any other person.
