This example visualizes stacked area chart data for total wages by country, showing how values change over time. The visualization uses D3.js v7 with an SVG rendering approach, fetching CSV data from a GitHub gist. The code employs `d3.area()` and `d3.stack()` to create the stacked areas, with `d3.scaleBand()` for the x-axis categories and `d3.scaleLinear()` for the y-axis scale. Color coding uses `d3.schemeCategory10` to distinguish each year's contribution to the total.
