This interactive network graph visualizes a small social network of six people, with nodes shaped according to job (circles for “Informatiker,” triangles for “Student,” rectangles for “Author”) and colored by gender. The node-link diagram is laid out using the force-directed physics of `d3.forceSimulation`, with link thickness proportional to the connection value. The visualization is built in React, uses SVG for rendering, and loads its JSON data via `d3.json`. Users can drag nodes to rearrange the layout, which the force simulation then re-optimizes in real time.
