First things first
Google Chrome and Firefox are recommended web browsers for working with this application. Unfortunately, Microsoft Internet Explorer and Apple Safari may not be able to support some of the web standards used here. While this app can render on both - desktop and mobile devices, it is much more usable on a large screen.
What does this app do
This App visualises Number of offences by suburb in Victoria, Australia and offence division and group, year ending March 2017. The original crime stats data can be downloaded from crimestatistics.vic.gov.au web site. Estimated Resident Population (ERP) and geographical polygons used in this app are based on Australian Census 2016 data (datapacks.censusdata.abs.gov.au).
How to use this app
The Application renders data as a multidimentional visualisation. All charts, including Crime Map are inter-connected and interactive, so you should be able to narrow down data to a subset of your interest within just a few mouse clicks. You can switch between Actual Offence Numbers and Crime Rate data views / measurements in the navigation bar. Crime Rate is a number of offences per 100,000 of population and calculated using the following formula:
\[\text"Crime Rate " = \text" Sum of Crime Offences for selected Suburb(s)" / \text" Total ERP for selected Suburb(s)" \text" * 100,000"\]
Here is a quick demo on how this app works:
