The ICE 7 Area Chart visualizes mobile purchase trends in India from 2010 to 2020. It combines a line and area chart to show the growth in purchases over time, with the line highlighting the trend and the filled area emphasizing the magnitude. The visualization uses D3 v5 APIs including `d3.scaleTime`, `d3.scaleLinear`, `d3.axisLeft`, `d3.axisBottom`, `d3.line`, `d3.area`, and `d3.curveBasis` to render the smooth curves. It loads CSV data from a GitHub gist and renders the result as SVG, with the line in orange and the area fill in yellow.
