I just switched from using a local copy of the minified version of d3.v3 to the development version. It worked fine when using the minified version, but using my local copy of <http://d3js.org/d3.v3.js> gives me the error in the title, referencing this line:

```
var € = Math.PI, µ = 1e-6, d3_radians = € / 180, d3_degrees = 180 / €;

```

When I include the hosted file, it works fine.
