This chapter covered several tools that you will use to render your visualizations: axes, which provide contextual information for charts; scales, which map abstract and quantitative domain data to pixel dimensions and other visual aspects; and colors, which are also used to encode information in a data visualization. These tools are part of five modules: d3-interpolate (introduced in the last chapter), d3-axis, d3-scale, d3-scale-chromatic, and d3-color.
We finished this chapter with a complete scatter and bubble chart example that used functions, methods, and properties from practically all of these modules.
Now that you know how to configure scales, axes, and colors, you are ready to explore shape and layout generator functions in D3 so that you can create classic line charts, stacked area charts, pie charts, doughnut charts, and any kind of visualization you can imagine...
