This network visualization maps relationships among six Game of Thrones characters, with links representing interactions and line thickness encoding connection strength. Nodes are colored by house affiliation using a categorical color scale. The code creates a force-directed graph using `d3.forceSimulation` with link distance, charge repulsion, and centering forces. SVG circles and text labels render the nodes, while `d3.drag` enables interactive repositioning. Link stroke widths map relationship values through `d3.scaleLinear`, and the layout updates continuously via the simulation's tick event.
