将matplotlib与NetworkX结合使用的优点是可以轻松生成PDF,PNG和SVG输出。
import networkx as nx
import matplotlib.pyplot as plt
G1 = nx.Graph()
G.add_nodes_from(["a", "b"])
G.add_edge("a", "b")
nx.draw_networkx(G)
plt.savefig("graph.pdf")
plt.savefig("graph.png")
plt.savefig("graph.svg")
如何修改此代码以生成HTML5 / Javascript Canvas代码?具体的代码,无论多么微不足道,比给定库的生根更有帮助。 Sigmajs似乎很有希望,如果不是因为缺乏文件。
答案 0 :(得分:0)
实现您想要的最直接的方法是使用Networkx将图表导出为GEXF:
G = nx.path_graph(4)
nx.write_gexf(G, "test.gexf")
然后在您的HTML中,您可以使用sigma.js GEXF解析器,如下所示:
<div id="container">
<style>
#graph-container {
top: 0;
bottom: 0;
left: 0;
right: 0;
position: absolute;
}
</style>
<div id="graph-container"></div>
</div>
<script>
/**
* The plugin sigma.parsers.gexf can load and parse the GEXF graph file,
* and instantiate sigma when the graph is received.
*
* The object given as the second parameter is the base of the instance
* configuration object. The plugin will just add the "graph" key to it
* before the instanciation.
*/
sigma.parsers.gexf('data/arctic.gexf', { // path to graph here
container: 'graph-container'
});
</script>
