This area chart displays the closing price of Google stock (GOOGL) over time, with the area under the line filled in steel blue. The visualization uses D3 v7 with an SVG rendering approach. The code loads CSV data from a GitHub repository using `d3.csv`, parses dates with `d3.timeParse`, and constructs the area with `d3.area()`. Axes are generated using `d3.axisBottom` and `d3.axisLeft`, while scales are set with `d3.scaleTime` and `d3.scaleLinear`.
