This visualization tracks stock quantities across multiple warehouse categories over time. It displays each movement as a horizontal bar, where green bars show net increases and gray dashed bars show decreases, with remaining totals labeled above. The chart uses D3 v5 with an SVG rendering approach, scaling linear amounts within a point-based time scale and a band scale for stock categories. Data is loaded from a JSON file and parsed with Moment.js for date formatting on the x-axis.
