This area chart visualizes a dataset loaded from a CSV file hosted on GitHub. The chart displays values over time, with dates parsed via `d3.timeParse` and a linear scale for the y-axis. The area path is generated using `d3.area` and rendered as a steelblue SVG path. Axes are created with `d3.axisBottom` and `d3.axisLeft`, and the chart is built with D3 v7.
