Learn what the Crossfilter library is, and how it can help power interactive web graphics.
The file as a whole is basically full of functions and taken together, the functions define new terms, a bit like a new language. For example, this function defines a crossfilter object with five properties: add, remove, dimension, groupAll, and size. We're going to be looking at these commands shortly. So this file defines what the crossfilter() command does, and then, say, the groupAll command as well, and various other terminology we're going to use.
And then we give it the location with the source property, src. And because we've saved crossfilter.js into the root, we have to go up a couple of levels before we can reach the file. And now we're good to go.
