我需要创建一个自定义形状的图形。例如：为了代表人口，我需要创建一个人体形状，在其中我将显示统计数据和数据。是否有任何javascript库可以帮助我这样做？ D3会帮助我吗？

感谢任何帮助。

谢谢。

您甚至可以尝试使用这种方法来使用两个图像并相互叠加。

让我们假设你想要一个人类的fontawesome图标作为图表，使用http://fa2png.io/将图标转换为.png图像，然后在下面的代码中使用它。

<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>

<script>

setInterval(function() {

我不知道“人形”的东西，我认为没有任何工具可以这样做。

但是，我遇到的最好和最接近的资源是Highcharts它有各种各样的饼图，样条线，条形图等。您需要以交互方式绘制数据。

我还建议您查看Google Charts。 Highcharts没有提供的一件事是基于地图的数据绘图。谷歌有一些名为GeoMap的数据，用于绘制信息，其位置与全球小城镇一样具体

有许多javascript库可以用来编写这样的东西，但是如果你发现任何“人口图”就像你开箱即用的那样，我会感到惊讶。

我最近在RaphaelJS上做了很多工作，根据你的用例，你可以用很少的工作从头开始编写一个简单的图形。考虑一下：

或者，一种简单的方法是设置重复的背景图像并根据您的计数改变DIV宽度/高度。好处是在任何浏览器中几乎没有性能损失，因为DIV高度和重复图像背景相当优化。

two divs: uninterrupted and partial

想法是选择一个瓷砖尺寸（例如：25 x 11）并将其分解为两个DIV。在上图中，第一个DIV在视觉上对两行负责，因为它们没有被分解（最大宽度）。第二个DIV显示最后一行，因为它的宽度代表部分数字。

function draw_guys( num, row_width ) {
    var whole = Math.floor( num / row_width ) * row_width;
    var rows = whole / row_width;
    var remainder = num - whole;

    // at this point, first div height should be 11 * rows,
    // and second div width should be remainder * 25
    // $("div1").css( ... etc.
}
