This network graph displays the relationships between the first twenty people in the SHL dataset and their associated attributes, including occupation and sleep disorder status. The visualization uses a force-directed layout with color-coded nodes—blue for persons, red for occupations, and yellow for sleep disorders—connected by gray links. Built with d3.v7, the code employs `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and drag interactions via `d3.drag`. Node tooltips appear on hover, and the SVG rendering includes labeled circles for each entity.
