This stacked area chart displays the distribution of educational degrees conferred in seven fields over time, with the x-axis representing years and the y-axis showing counts up to 200,000. It uses d3.stack() to layer the data, d3.area() and d3.scaleTime() to render the paths, and d3.scaleOrdinal() for the color palette. The visualization loads CSV data from a GitHub gist, draws SVG elements, and includes custom axis labels, with a legend implied by the colored layers.
