The ICE 7 Area Chart displays smartphone sales in millions from 2012 to 2021, using a smooth curve to highlight the upward sales trend over time. The chart renders as an SVG with a red area beneath a black line, generated via D3 v5’s `area()` and `line()` generators with `curveBasis` smoothing. It uses `d3.csv` to load data from a GitHub gist, and scales are defined with `scaleLinear`, while axes are drawn using `axisLeft` and `axisBottom`. The visualization includes clear axis labels and a title, making the sales progression immediately apparent.
