This scatterplot displays daily GrossAmount values over time, with each point colored by its price category through a categorical ordinal scale. The visualization includes an interactive color legend that highlights points matching the hovered value while fading others. Built with React and D3 v6, it uses `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map date, price, and color encodings, rendering circles as SVG marks. Data comes from NOAA, loaded via `d3.csv`, with axes generated by custom `AxisBottom` and `AxisLeft` components.
