This area chart visualizes student strength over a series of years, with a violet gradient fill beneath a smooth curve. The chart uses D3 v6 to load CSV data from a GitHub gist, parse dates with `d3.timeParse`, and render an SVG path generated by the `area` generator with a `curveBasis` interpolation. Axes are created via `axisBottom` and `axisLeft`, with grid lines and formatted tick labels, while the chart includes labeled axes and a title.
