D3-bind svg elements after Leaflet creates them?

[gordonwoodhull]

As reported here, d3.tip and other d3 stuff won't work on the shapes in dc.leaflet because the data isn't bound:

Since leaflet is creating the svg elements, not d3, the data is not attached and dc.leaflet.js is internally keeping a _dataMap to specify colors etc.

Could we bind those elements post hoc? Or is this dangerous?

Does leaflet have its own notion of data binding?
