text() calls don't work on HTML elements

[sun16]

IE7/8 doesn't support the textContent attribute (see selection-text.js).

var div = d3.select('body').append('div');
div.text('hi');
console.log(div.text()); // should print hi

Instead, I recommend using innerText as it's the property that mimics textContent the closest.

Unfortunately DOM elements in IE7 aren't the same as regular JS objects , so you can't just change their prototype and shim textContent. I simply replace textContent with innerText in my build.
