Creating scatter plots with NVD3
If you've been following along from the previous recipes in this chapter, you'll now have a complete web application stack ready, and you can use it to create charts and graphs for the Web.
For this recipe, we'll create a scatter plot of the US census racial data that we saw in Chapter 6, Workin with Incanter DataSets, in the Grouping data with $group-by recipe. In fact, this will be the same recipe as we saw in Chapter 10, Working with Unstructured and Textual Data, only this time we'll create a web page.

You can use it to transform data into tables or charts. It is pretty low-level though. With D3, we will create many of the actual elements. We'll do this in a later recipe, but for now, we'll use the NVD3 library (http://nvd3.org...
