This example visualizes an inventory cycle by simulating items as they move through a process flow, with each item’s location mapped to x-y coordinates on an SVG canvas. The animation, driven by d3.timer, shows items transitioning between marked points (point 1, 2, 3) along elliptical paths, with each item’s shape (square, triangle, circle) representing its silhouette. The code uses D3 v4 for DOM manipulation and transitions, generating paths via custom functions and updating attributes for each animation frame. The simulation randomly spawns items and updates their positions based on event timestamps, creating a continuous flow through the cycle.
