[英]How to generate D3.js circular dendrogram code from Python
The following figure is generated with D3.js. 使用D3.js生成下图。
based on the code here : 根据这里的代码:
<!DOCTYPE html>
<meta charset="utf-8">
<title>Flare Dendrogram</title>
<style>
.node circle {
fill: #fff;
stroke: steelblue;
stroke-width: 1.5px;
}
.node {
font: 10px sans-serif;
}
.link {
fill: none;
stroke: #ccc;
stroke-width: 1.5px;
}
</style>
<body>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
var radius = 960 / 2;
var cluster = d3.layout.cluster()
.size([360, radius - 120]);
var diagonal = d3.svg.diagonal.radial()
.projection(function(d) { return [d.y, d.x / 180 * Math.PI]; });
var svg = d3.select("body").append("svg")
.attr("width", radius * 2)
.attr("height", radius * 2)
.append("g")
.attr("transform", "translate(" + radius + "," + radius + ")");
d3.json("/d/4063550/flare.json", function(error, root) {
var nodes = cluster.nodes(root);
var link = svg.selectAll("path.link")
.data(cluster.links(nodes))
.enter().append("path")
.attr("class", "link")
.attr("d", diagonal);
var node = svg.selectAll("g.node")
.data(nodes)
.enter().append("g")
.attr("class", "node")
.attr("transform", function(d) { return "rotate(" + (d.x - 90) + ")translate(" + d.y + ")"; })
node.append("circle")
.attr("r", 4.5);
node.append("text")
.attr("dy", ".31em")
.attr("text-anchor", function(d) { return d.x < 180 ? "start" : "end"; })
.attr("transform", function(d) { return d.x < 180 ? "translate(8)" : "rotate(180)translate(-8)"; })
.text(function(d) { return d.name; });
});
d3.select(self.frameElement).style("height", radius * 2 + "px");
</script>
Is there a way I can use Python to generate the above exact figure (HTML)? 有没有办法可以使用Python生成上面的确切数字(HTML)?
Assuming that you want to avoid having to write javascript and using python instead, you could have a look at pyjs. 假设您想要避免编写javascript并使用python,您可以查看pyjs。 From their website :
从他们的网站 :
pyjs contains a Python-to-JavaScript compiler, an AJAX framework and a Widget Set API. pyjs started life as a Python port of Google Web Toolkit, the Java-to-JavaScript compiler.
I haven't used it and am unsure how you would go about including the d3 library. 我没有使用它,我不确定你将如何包括d3库。 However their wiki has the following page:
但是他们的wiki有以下页面:
https://github.com/pyjs/pyjs/wiki/Calling-a-jQuery-component-from-Pyjs https://github.com/pyjs/pyjs/wiki/Calling-a-jQuery-component-from-Pyjs
That article might give you an idea of whether pyjs is useful to you. 那篇文章可能会让你知道pyjs是否对你有用。

Not too dissimilar to pandita's suggestion , you could use Brython , which allows you to run Python in a web browser. 与pandita的建议没什么不同,您可以使用Brython ,它允许您在Web浏览器中运行Python。 Some sample skeleton code (using D3.js; I don't know of any Python libraries that give you a dendogram result as good as D3.js.):
一些示例框架代码(使用D3.js;我不知道任何Python库为您提供与D3.js一样好的树形图结果):
<!DOCTYPE html>
<meta charset="utf-8">
<title>Flare Dendrogram</title>
<style>
/* CSS goes here */
</style>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script src="brython.js"></script>
<script type="text/python">
#
# Python code to generate dendogram here
# (equivalent to the sample JavaScript code provided)
#
</script>
<body onload="brython()">
</body>
</html>
But this doesn't seem like a great solution. 但这似乎不是一个很好的解决方案。
