This site contains easily downloadable TopoJSON files of data for UK boundaries, ideal for creating choropleth maps of UK areas. GeoJSON files are available in the Github repository
All data is converted from the generalised clipped boundaries provided by the Office of National Statistics, National Records Scotland and Ordnance Survey. Data has been converted to GeoJSON from original shapefiles using ogr2ogr, then converted to TopoJSON using topojson.
