This interactive food web depicts the feeding relationships among seven animals in a simple ecosystem, with nodes colored by trophic level (producer, herbivore, omnivore, carnivore, apex predator) and directed arrows showing energy flow. The visualization uses D3.js v7 with an SVG renderer, placing nodes initially in a static layout while allowing users to drag and reposition each animal. Edges are drawn as lines with arrowhead markers, and the legend clarifies the color coding for each ecological role.
