Programming Assignment 1

Taste of Visual Analytics:Mapping Reported Crimes in Penn State

Background

Required by federal laws, Penn State makes the public aware of reported crimes on campus. Relevant

information is provided on a website: http://police.psu.edu/daily-crime-log. While people can browse

the website to know what crimes have been reported, when and where they happened, it is still a

challenge for people who try to understand more about on-campus crimes, such as the distribution of

the crimes across campus.

Objective

Your assignment is to build a map-based tool to show the locations of these reported crime. Figure 1

shows a result of this assignment.

Figure 1: A result of the assignment.

In this figure, each reported crime is represented as a marker ,and the location of the marker

indicates the location of the reported crime. When the cursor is over a marker, the name of its location

pops out.

Data

The crime data used for this assignment can be found in the PSU_ReportedCrimes.txt document under

the folder of
\up.ist.localCoursesSpring2017IST402ProgrammingAssignmentDataSetsAssignment1_TasteofVisualAnalytics

Delivery

An HTML document should be submitted to the CANVAS dropbox.
