In this chapter, we've set up our working environment and introduced the first couple of concepts of D3. We've showed that there is a standard pattern for binding data to elements, and how we can use D3 to handle new elements, update existing elements, and how to remove obsolete elements. We've also created our first visualization in this chapter. We've used a standard CSV file, and converted that to a bar chart, complete with custom colors, text elements, and a set of axes. Throughout this chapter, we've touched upon a couple of D3 APIs and concepts, such as d3.selectAll, d3.axisBottom, and even explored a part of how D3 handles scales (d3.linearScale).
In the next chapter, we'll continue with the subjects we've seen so far, and look more closely at how you can use D3 to create different kinds of charts.
