I metodi D3 possono aggiungere stili alle etichette delle barre. L'attributo `fill` (riempimento) imposta il colore del testo per un nodo `text` . Il metodo `style()` imposta regole CSS per altri stili, come `font-family` o `font-size` .

Imposta la dimensione `font-size` degli elementi `text` a `25px` e il colore del testo a rosso.

Le barre dovrebbero avere tutte un colore di riempimento (`fill` ) rosso.

```js
assert($('text').css('fill') == 'rgb(255, 0, 0)');
```

Le etichette dovrebbero avere tutte un `font-size` di `25` pixel.
