You should use ES Map instead of Object.

@mbostock correct me if I'm wrong, but you're asking me to just splice off the $
from the start of the keys?

Sorry I wasn't familiar with the new data structure, thanks for the information that's really interesting.

No, you shouldn’t be iterating over the properties on a d3.map instance, as those are private; you should be using map.keys.
