Panoramica

Un albero di parole mostra più sequenze parallele di parole. Può essere utilizzato per mostrare le parole che seguono o precedono più spesso una parola di destinazione (ad esempio, "I gatti sono...") o per mostrare una gerarchia di termini (ad es. un albero decisionale).

I sistemi di messaggistica di Google sono in grado di elaborare rapidamente grandi quantità di testo. I sistemi moderni dovrebbero essere in grado di gestire quantità di testo in formato nuovo senza un ritardo significativo.

Nota: la struttura ad albero delle parole è in versione beta e nelle versioni future di Google Class potrebbero essere apportate modifiche sostanziali.

Gli alberi di parole vengono visualizzati nel browser utilizzando SVG, il che significa che funzioneranno in tutti i browser moderni (ad es. Chrome, Firefox, Opera e Internet Explorer 9 e versioni successive). Come per tutti i grafici Google, nella visualizzazione ad albero delle parole chiave vengono visualizzate le descrizioni comando quando l'utente passa il mouse sopra i dati.

Esempio semplice

Supponiamo che tu abbia raccolto un insieme di frasi sui gatti (ad es. "i gatti mangiano i topi", "i gatti sono meglio dei gattini") e vuoi evidenziare gli attributi più importanti della serie.

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>
