This visualization by KSivani30 uses a multi-series area chart to display the proportion of ratings across various music genres. It shows how rating proportions differ per genre, with each colored area representing a separate data column from the loaded CSV source. The chart is rendered as an SVG using the d3 framework and draws the areas with the `d3.area` generator, applying a category-10 color scheme for differentiation. Axes are labeled "Genres" and "Rating Proportion" via appended text elements, and a legend identifies each series.
