How to use D3js on server side to generate SVG directly?
I made an example in case that helps:
#!/usr/bin/env nodevar d3 = require("d3"), jsdom = require("jsdom");const { JSDOM } = jsdom;const { document } = (new JSDOM('')).window;global.document = document;var body = d3.select(document).select("body");var width = 300;var height = 300;var svg = body.append("svg") .attr("width", width) .attr("height", height);svg.append("line") .attr("x1", 100) .attr("y1", 100) .attr("x2", 200) .attr("y2", 200) .style("stroke", "rgb(255,0,0)") .style("stroke-width", 2);const fs = require('fs');fs.writeFileSync("test.svg", body.node().innerHTML)
You may look this post. in these posts, some similar question has reached the answer.
