This fork of the GraphLayout example displays a zoomable, force-directed graph using D3.js v5. Node positions come from a CSV file and are drawn as colored circles on an SVG canvas, while edges are rendered as lines. The node color encodes a categorical `k` value via `d3.scaleOrdinal` with a `schemeRdYlGn` color scale. Users can interact with the graph using the `d3.zoom` function to pan and scale the layout.
