Chapter 5. Click-click Boom! Applying Interactivity to Your Map

In the previous chapter, you learned what is needed to build a basic map with D3.js. We also discussed the concepts of enter, update, and exit and how they apply to maps. You should also understand how D3 mix-and-matches HTML with data. However, let's say you want to take it a step further and include more interaction on your map. We covered just the tip of the iceberg with click events in the previous chapter. Now, it's time to dig deeper.

In this chapter, we will expand our knowledge of events and event types. We will progress experiment by experiment, building on what we've learned. The following topics are covered in this chapter:

  • Events and how they occur

  • Experiment 2 – tooltips with visualizations
  • Experiment 3 – panning and zooming
  • Experiment 4 – orthographic projections
  • Experiment 5 – rotating orthographic projections
