This scatterplot visualizes Seattle weather data, plotting daily maximum temperature against precipitation and encoding weather type by color. Built with D3 v7 and React, it uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `schemeTableau10` for categorical colors, and `d3.axisBottom`/`d3.axisLeft` for labeled scales. The SVG renders circles with fixed radius and opacity, includes a weather legend, and loads data from a CSV file.
