This example visualizes stock movements over time using a band scale for time and a color-coded bar chart for quantities. It plots quantities across different storage locations, with horizontal links showing transfer origins between elevators and destinations. The visualization uses D3 v5 with SVG rendering, employing `scalePoint` for time, `scaleBand` for locations, `scaleLinear` for quantities, and `linkHorizontal` for the flow paths. Data comes from a JSON file containing timestamps, quantities, and location references.
