This example shows a force-directed network graph of nodes and links, displaying a dataset of photograph-related entities and their connections. The visualization loads graph data from a JSON file and uses D3 v3’s force layout to position the elements dynamically. Nodes are rendered as SVG groups containing a GitHub favicon image and a text label, while links appear as simple gray lines. The simulation applies gravity, charge, and link distance settings to arrange the layout, and node positions update on each tick event.
