This area chart displays the yearly average number of hotel bookings, using a light blue-green filled area with a darker stroke to emphasize the trend over time. The visualization is built with D3 v5, using `d3.scaleBand` for the categorical x-axis of years, `d3.scaleLinear` for the y-axis of booking counts, and the `d3.area()` generator to create the filled path. Data is loaded from a CSV file hosted on GitHub, and the SVG rendering includes labeled axes and a title, with the area’s base anchored at the bottom of the chart.
