In this chapter, we discussed GeoJSON, what it's used for, and why it differs from more general JSON data.  We've also covered how to use D3 to create a projection and render GeoJSON data as a map.  Using this information, we can create all sorts of interesting maps of countries, cities, towns, or any area that we have GeoJSON data for.  We can use different projections to view this data in interesting ways

Congratulations! You've made it to the end of the book. Now, go and create amazing visualizations.
