Please click United States, Japan or their states/prefectures to see zoom animation. 1 Gather Geo Data d3.js doesn't come with geo data, so let's get country, state/province and city data first. Natural Earth is one of the best sources for Earth data. When you go to the download page, there are three data scales: 1:10m, 1:50m and 1:110m. 1:10m has the most detailed data but is the largest file size, which is not usually suitable for web application data. 2 Shapefile GeoJSON Topojson Once you download and unzip them, you can find a bunch of files with different file extensions. Install GDAL To convert a shapefile into GeoJSON, we'll use a command line tool, ogr2ogr in Geospatial Data Abstraction Library - GDAL.
> brew install gdal Install Topojson Another CLI tool that we use will use is topojson, which converts GeoJSON to Topojson. > npm install -g topojson 3 Convert Files Let's start with the countries shapefile.

Automatic Projection Tiles. What are Tiles?
Most modern Web maps use raster or vector tiles to allow zooming to very large scales while only loading a fraction of the whole map. The projection of choice for these tiles is the Mercator projection, and they are typically arranged in the form of a recursively subdivided quadtree. It would be a shame to limit ourselves to a single map projection, when there are so many to choose from! But how do we figure out which tiles to retrieve? How it Works My initial attempts involved inverting the viewport polygon to figure out which tiles overlap with it. Mike Bostock then pointed out that the tiles can be traversed recursively (in logarithmic time, since it’s a tree), using a custom geometry stream to detect if a tile is visible or not.
Starting with a single large tile covering most of the globe, this recursively rejects large swathes of the quadtree, and is very fast even at a zoom level of 18!
