This area chart displays stock prices over time, with the x-axis representing years and the y-axis representing stock price values. The visualization uses a filled area path with a light purple fill and a green stroke to encode the data trend. The code relies on D3 v4’s `d3.area`, `d3.scaleTime`, `d3.scaleLinear`, and axis functions to render the SVG. Data is loaded from a CSV file hosted on GitHub, and the chart is drawn within an SVG container.
