unicode identifiers?

[tj]

Yes, JavaScript supports Unicode identifiers.

If you’re using d3.v3.js (non-minified), you need to specify the UTF-8 charset. That is typically done either by:

<meta charset="utf-8">

Or:

<script src="http://d3js.org/d3.v3.js" charset="utf-8"></script>

If you’re using d3.v3.min.js, the minified file is escaped with UglifyJS’s --ascii command-line option, so it is not dependent on the charset.
