A horizontal bar chart ranks countries by their 2017 fossil CO2 emissions, sorted in descending order with purple bars on a gold-ruled grid. Built with React and d3.v5, the visualization uses `csv()` to load the dataset, `scaleBand()` for the country axis, and `scaleLinear()` for the emissions axis. SVG rendering is handled through ReactDOM, with gridlines and labels generated via `xScale.ticks()` and map iterations.
