In this chapter, we described the characteristics of good dashboards and discussed the process behind the design and implementation of dashboards. We learned good practices to create effective dashboards. We also created an example dashboard to monitor the performance of the students in a class, including sections to assess the scores of individual students, courses, and classes.

In the next chapter, we will learn how to use GeoJSON and TopoJSON files to create maps with D3. We will learn about projections, how to use maps to display data, and how to integrate D3 with Mapbox.
