This visualization shows a network graph of employee relationships, with circles representing individuals and lines connecting each person to their parent node. The graph uses a force-directed layout driven by `d3.forceSimulation`, applying link distance, charge, and centering forces to position nodes. Data loads from a CSV file hosted on a Gist, and the code builds nodes and links from the Name and Parent columns. Rendered as SVG, the graph updates node positions and link coordinates on each simulation tick, with styling applied to links, circles, and text labels.
