Part 3 Intricate data visualizations

So far in this book, we’ve been exploring relatively simple types of data visualizations: bar charts, scatterplots, donut charts, and so on. Because of the philosophy behind it, D3 allows us to build much more complex data visualizations. The huge advantage this gives us is that we don’t need to learn a new library for networks and another one for maps. Instead, the techniques you’ve learned so far will still be helpful for those data representation types.

In chapter 11, we’ll work with hierarchical data of the most common languages spoken today and visualize them with a circle pack and a tree chart. In chapter 12, we’ll look at the dynamics between the characters from the play Romeo and Juliet with network visualizations. Finally, in chapter 13, we’ll ask ourselves if the country in which you were born is correlated with your chances of ever winning a Nobel Prize by creating maps.
