Mapping Sydney's creative clusters
The creative sector should be seen as more than an extra to a modern city, it should be viewed as an economic engine.
This map visualises creative professionals' geographical concentration within New South Wales. The most suitable visual encoding for this information is a heat-map and creating one with modern web mapping libraries is trivial, given an appropriate dataset. This wasn't the case however as I only had number of registrations per postcode (for better and worse as I would have anonymised the dataset anyway).
My solution was to randomly generate coordinate pairs, one for each registered artist within the given postcode boundary. It should be noted, that many postcodes are defined as multi-polygons, which had to be identified and the coordinate pairs distributed within them to match the total registrations of the given postcode.
