how does your templating approach handle this task?

1.json

{
    "settings" : {
        "foo" : "low",
        "bar" : "high",
        "baz" : "low"
    }
}

2.html

Scenario:
Given the data structure above in "1.json", how would you
use a templating engine to generate this snippet of html
as a string? NOTE: the spirit of this question is to
generate a string of markup with a template engine, NOT
to do DOM manipulation. Imagine needing to generate this
kind of markup server-side to send over the wire.

<h1>Settings</h1>
<h2>foo</h2>
<input type="radio" name="foo" value="low" checked> low
<input type="radio" name="foo" value="high"> high
<h2>bar</h2>
<input type="radio" name="bar" value="low"> low
<input type="radio" name="bar" value="high" checked> high
<h2>baz</h2>
<input type="radio" name="baz" value="low" checked> low
<input type="radio" name="baz" value="high"> high
