This is a contour map of the Shetland Islands, off the north coast of Scotland. It was made using terrain data from the Ordnance Survey and d3js.
This is a visualization of buildings in the London CBD based on land use. Data is from the European Environment Agency's Urban Atlas which provides land use and land cover data for Large Urban Zones.
Building data is from the Ordnance Survey. Land cover percentages are based on the level of soil sealing.
Made with d3js.
Flickr activity fingerprints for London, New York City and Paris. Each dot represents a longitude/latitude location of 0.002 degrees with its radius proportional to image upload activity for July 2012. Each map's scale is the same allowing for a proper comparison. London is quite dispersed whilst Paris is fairly compact and you can clearly see Manhattan in NYC.
These maps are heavily inspired by Anil Bawa-Cavia's Social Activity Fingerprints for the Foursquare network. They are found at http://urbagram.net/images/LDN-NYC-PAR-fingerprints-l.gif.
These maps were created using d3.js and the flickr api, with screenshots using PhantomJS
London traffic is a collection of maps visualizing traffic density in and around London. Data from 2001 and 2011 has been used, separated by transportation type.
They were built using d3js with data from open street maps and the Department for Transport traffic counts. Traffic density was visualised using svg masking. An example of the source code can be found at this gist. Shapefiles were generated to geojson and then topojson using GDAL and topojson respectively. They use AADF (average annual daily flow) figures for major roads around greater London. It is a demonstration of how d3 can be used to make detailed maps for comparisons.

The sandbox contains examples of techniques I am working on. They are not intended to be complete visualizations as they don't really tell a story, but rather indicate works in progress.
