This example shows a visualization using data loaded from `data.csv`, rendered with D3 v6. It constructs a force-directed network layout using `d3.forceSimulation`, with forces for charge, center, and link positioning, and displays nodes and edges as SVG elements. The code reads the CSV with `d3.csv`, parses numeric node attributes, and binds link and node data to the simulation. Rendering relies on D3’s selection and data-join methods to create circles and lines, with forces updating positions on each tick.
