This area chart visualizes student marks distribution using D3.js v7, rendering an SVG with a steelblue gradient fill beneath the line. The chart loads CSV data from a GitHub gist, parsing label and students columns, then maps them to x and y axes using `scaleLinear`. It constructs the area path via `d3.area()`, applies a `linearGradient` for the fill, and labels axes as “Total Marks” and “Students”. Styling includes a bordered, rounded container background.
