1,077 PointsI'm confused. Huston types 'circles', not 'circle', into the console. Shouldn't 'circle' always remain singular?
In the data binding lesson, Huston talks about creating an svg circle for every data point in the databinding.html doc. However, when he demonstrates how to double-check the data in the javascript console, he very explicitly types 'circles.' Am I missing something? Shouldn't 'circle' always be singular?

230,688 PointsHe explains this is known as a "ghost selection" which is empty since there are (initially) no elements of that type. While his use of "circles" may have been accidental, if I understand what is happening he could potentially use ANY identifier that does not already exist.

14,384 PointsYou are right, the code he writes will fail. If you run 'viz.selectAll('circle') you will see the array he's talking about.
