javascript圖表繪制庫：plotly.js

Plotly.js 是一個構建在d3.js和stack.gl,之上的開源 JavaScript圖表繪制庫。plotly.js是一個高級，聲明式的圖表庫。 plotly.js支持20多圖表類型，包括3D圖表，統計圖表，和SVG地圖。

Plotly.d3.csv('https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv', function(err, rows){
      var YEAR = 2007;
      var continents = ['Asia', 'Europe', 'Africa', 'Oceania', 'Americas'];
      var POP_TO_PX_SIZE = 2e5;
      function unpack(rows, key) {
          return rows.map(function(row) { return row[key]; });
      }

      var data = continents.map(function(continent) {
          var rowsFiltered = rows.filter(function(row) {
              return (row.continent === continent) && (+row.year === YEAR);
          });
          return {
              mode: 'markers',
              name: continent,
              x: unpack(rowsFiltered, 'lifeExp'),
              y: unpack(rowsFiltered, 'gdpPercap'),
              text: unpack(rowsFiltered, 'country'),
              marker: {
                  sizemode: 'area',
                  size: unpack(rowsFiltered, 'pop'),
                  sizeref: POP_TO_PX_SIZE
              }
          };
      });
      var layout = {
          xaxis: {title: 'Life Expectancy'},
          yaxis: {title: 'GDP per Capita', type: 'log'},
          margin: {t: 20},
          hovermode: 'closest'
      };
      Plotly.plot('my-graph', data, layout, {showLink: false});
  });
