Descripción general

Un árbol de palabras representa varias secuencias paralelas de palabras. Se puede usar para mostrar qué palabras suelen seguir o preceder a una palabra objetivo (p.ej., “Cats are...") o para mostrar una jerarquía de términos (p.ej., un árbol de decisión).

Los árboles de palabras de Google pueden procesar grandes cantidades de texto con rapidez. Los sistemas modernos deben poder manejar cantidades de texto novedosas sin una demora significativa.

Nota: El árbol de palabras se encuentra en versión Beta y es posible que esté en revisión importante en versiones futuras de los gráficos de Google.

Los árboles de palabras se renderizan en el navegador mediante SVG, lo que significa que funcionará en todos los navegadores modernos (p.ej., Chrome, Firefox, Opera e Internet Explorer 9+. Al igual que todos los gráficos de Google, los árboles de palabras muestran información sobre la herramienta cuando el usuario se desplaza sobre los datos.

Un ejemplo simple

Supongamos que recopilaste un conjunto de frases sobre gatos (p.ej., "gatos coman ratones", "los gatos son mejores que los gatitos") y quieres destacar los atributos más importantes del conjunto.

function drawChart() {
        var data = google.visualization.arrayToDataTable(
          [ ['Phrases'],
            ['cats are better than dogs'],
            ['cats eat kibble'],
            ['cats are better than hamsters'],
            ['cats are awesome'],
            ['cats are people too'],
            ['cats eat mice'],
            ['cats meowing'],
            ['cats in the cradle'],
            ['cats eat mice'],
            ['cats in the cradle lyrics'],
            ['cats eat kibble'],
            ['cats for adoption'],
            ['cats are family'],
            ['cats eat mice'],
            ['cats are better than kittens'],
            ['cats are evil'],
            ['cats are weird'],
            ['cats eat mice'],
          ]
        );

var options = {
          wordtree: {
            format: 'implicit',
            word: 'cats'
          }
        };

var chart = new google.visualization.WordTree(document.getElementById('wordtree_basic'));
        chart.draw(data, options);
      }
    </script>
  </head>
  <body>
    <div id="wordtree_basic" style="width: 900px; height: 500px;"></div>
