This example demonstrates a force-directed graph that can be zoomed and dragged. A circle within an SVG group responds to mouse interaction, with the SVG changing its cursor style to indicate draggable zones. The visualization uses D3 v6 to create three separate SVG elements, applies a linear color scale mapping scores to colors like lime, yellow, and red, and employs a power scale for sizing nodes. A zoom effect is implemented via `d3.zoom()`, which updates the SVG’s transform attribute on zoom events.
