587d7faa367417b2b2512bd3 Estilizar as etiquetas do D3 6 301492 style-d3-labels

--description--

Os métodos do D3 podem adicionar estilos às etiquetas das barras. O atributo fill define a cor do texto para um nó text. O método style() define as regras do CSS para outros estilos, como font-family ou font-size.

--instructions--

Defina o font-size dos elementos text para 25px e a cor do texto para "red" (vermelho).

--hints--

As etiquetas devem ter a propriedade fill com a cor "red".

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

As etiquetas devem ter um font-size de 25 pixels.

assert($('text').css('font-size') == '25px');
