Description

Os métodos D3 podem adicionar estilos aos rótulos da barra. O atributo de fill define a cor do texto para um nó de text . O método style() define regras CSS para outros estilos, como "font-family" ou "font-size".

Instructions

Defina o font-size da font-size dos elementos de text para 25px e a cor do texto para vermelho.

Tests

tests:
  - text: As etiquetas devem ter uma cor de <code>fill</code> vermelha.
    testString: 'assert($("text").css("fill") == "rgb(255, 0, 0)", "The labels should all have a <code>fill</code> color of red.");'
  - text: Todas as etiquetas devem ter um <code>font-size</code> de <code>font-size</code> de 25 pixels.
    testString: 'assert($("text").css("font-size") == "25px", "The labels should all have a <code>font-size</code> of 25 pixels.");'
