This line chart visualizes the closing price of Netflix stock over time, using a smooth curved line rendered in an SVG element. The chart is built with D3.js, employing `scaleLinear` for both axes, `extent` to compute domains, and `line` with `curveBasis` for the smoothed path. Data is loaded via `csv` from a GitHub gist containing historical stock data. The visualization includes labeled X and Y axes, a title, and horizontal gridlines with tick marks extending across the plot area.
