This area chart visualizes the distribution of employee counts across different job positions, with positions sorted alphabetically along the x-axis and counts on the y-axis. The chart uses D3.js v7 with an SVG rendering approach, employing `d3.rollup` to aggregate the CSV data by position and `d3.area()` with `curveMonotoneX` to draw the filled path. Axis labels are rotated for readability, and the data source is a GitHub gist containing department records.
