This area chart visualizes the relationship between weight (kg) and price (USD) for items in the ICE-7 dataset, with weight on the x-axis and price on the y-axis. The chart uses a steelblue, semi-transparent filled area to show price variation across the sorted weight range. Built with D3.js v7, it loads CSV data from a GitHub gist, applies linear scales via `d3.scaleLinear`, and draws the area using the `d3.area()` generator along with `d3.axisBottom` and `d3.axisLeft` for axes.
