This visualization shows a social network of friends centered around Sai Nikitha, with nodes representing people (and the country India) connected by friendship links. It uses the D3.js v6 library, specifically `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to position the nodes. Draggable pink circles with text labels are rendered as SVG elements, and links appear as yellow lines with arrow markers. The data comes from an external JSON file containing node and link definitions, with mouseover interactions to highlight connected nodes via the `nodeHover` class.
