This interactive scatter plot visualizes the relationship between trip distance and pickup hour, with color encoding for the day of the week. The visualization uses React and D3.js v5 to render SVG circles, implementing an interactive legend that highlights a selected weekday by dimming all other data points. Using `d3.scaleLinear` for axes, `d3.scaleOrdinal` for categorical color mapping, and `d3.csv` for loading the dataset, the chart supports hover-based tooltips via SVG `<title>` elements and dynamic filtering of the rendered marks.
