The power of data visualization is becoming increasingly more robust and intricate in nature. The demand to deliver a variety of complex information has lead to the development of highly responsive visual platforms. Libraries such as d3 are providing increased flexibility to work along multiple web technology stacks (HTML, CSS, SVG) allowing for nearly unlimited customization and capacity to handle large datatypes.
In this development, a combination of d3 and Leaflet is used to provide a data-driven visualization within an easy to use mapping engine framework; made possible through the developments of Asymmetrik. This collection of plugins, has allowed the creation of dynamic hexbin-based heatmaps and dynamically update/visualize transitions.
The web mapping application is avaiable at: HexBinning Ontario
