This dashboard combines a React-rendered cartoon face with a D3.js streamgraph. The Face component uses SVG circles and an arc path to draw eyes, a mouth, and a yellow background circle, with randomized eye size on each render. The Streamgraph builds a stacked area chart from a CSV dataset, using `d3.stack` with `stackOffsetSilhouette` and `d3.area` to create overlapping series. The graph includes axis labels, a color scale via `d3.scaleOrdinal`, and an interactive tooltip that highlights areas on hover.
