Geographic maps tend to be encoded such that the shape, size, and position are fixed, but these variables are crucial to creating a good visualization. In this video, we shall convert raw geographic data to GeoJSON, a format that D3.js can then manipulate to our liking. 
• Get and unzip the raw data from the Natural Earth website 
• Convert raw geographic data to GeoJSON with GDAL, installing it if necessary. Inspect the GeoJSON file to get an understanding of what we'll be working with 
• Compress the GeoJSON file to just the necessary elements using TopoJSON, installing it if necessary
