Visualizing Geographical Data

In this chapter, you will learn how to process geographical data using files in standard vector formats for web-based geographical information systems (GIS), such as GeoJSON and TopoJSON. You will then use these to render interactive map visualizations using D3.js. You will learn how to display this data using a map projection of your choice and decorate it with graticules, meridians, parallels, labels, and thematic data that's been extracted from the files. You can choose the projection that best fits the purpose of your map from a very large collection of projection functions that are available in the d3-geo, d3-geo-projection, and d3-geo-polygon modules. Combining it with other data files, you can create dot distributions, bubble charts, flow diagrams, choropleths, and other thematic maps.
