This area chart visualizes monthly website visitor counts using a steel-blue filled area beneath a line. The chart employs an SVG rendering approach with D3.js v7, using `d3.area()` to generate the path and `d3.scalePoint()` for the categorical month axis. Data is loaded remotely from a CSV file via `d3.csv()`. The visualization includes labeled axes for month and visitor numbers, with margins defining the plotting area.
