This area chart visualizes Bitcoin rate flow over time, with timestamps on the x-axis and bitcoin values on the y-axis. It uses D3 v5's `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate a smooth, filled path. Axes are rendered with `axisBottom` and `axisLeft`, and the data is loaded from a CSV file via `csv()`. The SVG is 920 by 400 pixels, styled with CSS classes, and built using React within the VizHub framework.
