This stacked bar chart shows agricultural trade data for Afghanistan from 2014 to 2018, displaying Import, Export, Production, and Consumption values per year. Each bar segment represents one category, with colors distinguishing the four metrics. The visualization uses D3.js v7 with `d3.stack()` to compute the stacked series, `d3.scaleBand()` for the x-axis years, and `d3.scaleLinear()` for the y-axis values. Data is hardcoded in the script rather than loaded from the accompanying CSV file. The chart renders as SVG with axis generators `d3.axisBottom()` and `d3.axisLeft()`.
