This area chart visualizes website traffic over a 100-day period, showing a clear upward trend in daily visits. The visualization uses a semi-transparent steelblue fill to represent the area beneath the line, with labeled axes for Day and Number of Visits. Built with D3 v7, the code loads data from a CSV file and renders the chart as an SVG using the `d3.area` generator, while `d3.scaleLinear` and `d3.axisBottom`/`d3.axisLeft` handle the scaling and axes.
