This area chart visualizes employee entry counts throughout the day, with a smooth cardinal curve connecting data points along a band scale for time and a linear scale for entries. The SVG rendering uses D3 v7 with `d3.area()` and `d3.curveCardinal` to generate the filled path, while `d3.axisBottom` and `d3.axisLeft` provide labeled axes. Data is loaded asynchronously from a remote CSV file hosted on GitHub via `d3.csv`.
