I have somehow a technical question. I would like to know if there is a possibility to style a d3 element with jQuery.

For instance a "Collatz Graph" example from the d3 site <http://www.jasondavies.com/collatz-graph/> is producing a circle - like nodes with small labels.

In that case the numbers 1, 2, 3 and so on. The number is nothing more than a piece of code e.g.

```
 <text dy=".31em" text-anchor="start" transform="rotate(90)translate(8)">32</text>

```

How could I style this element with jQuery? e.g. adding a red border by clicking it?

Obviously I would need a class or id in the `<text ... >` and proceed as follows:

```
 $(".nome_class").click(function() {
    $(this).css( "border", "3px solid red" );
 }); 

```

In my code, both d3 is working (I can see a graph) and jQuery is working (I can for instance style or do something else with the regular HTML elements). BUT when I try style d3 element I get no result. 

I will be very grateful for any hint or advice.
