VistasD3.JS - svg shown in github editor, but not in Visual Studio Code - why?
As a D3 beginner, I am currently making a tutorial, using the Github editor. So far everything works. However, when I use the code one to one in my IDE, the black circles are not displayed? How can this be??

import {select, forceSimulation, forceManyBody, forceLink, forceCenter} from "d3";

const svg = select("#container");
const width = +svg.attr("width");
const height = +svg.attr("height");
const centerX = width / 2;
const centerY = height / 2;
const links = [
{"source": 0, "target": 1}, // Alice → Bob
{"source": 1, "target": 2} // Bob → Carol
];
const simulation = forceSimulation(nodes)
.force("charge", forceManyBody())
.force("link", forceLink(links))
.force("center", forceCenter(centerX, centerY));
const circles = svg.selectAll("circle").data(nodes).enter().append("circle").attr("r", 30);
simulation.on("tick", () => {
circles.attr("cx", d=>d.x)
circles.attr("cy", d=>d.y)
});
