plotly.js 介绍
Plotly.js 是开源的 JavaScript 图表库，它基于 d3.js 和 stack.gl
。是一个高层次的、描述性的图表库。 plotly.js 带来20种图表类型，包括 3D 图表，统计图表，和 SVG 地图。
实例代码：
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});
});
