A React-based scatter plot visualizes COVID-19 metrics from a May 2020 dataset, with dropdown menus controlling which two attributes (e.g., new cases, total deaths) map to the x- and y-axes. Points are colored by continent using a d3.scaleOrdinal color scale and a custom color legend. Built with d3.v5 for scales, axes, and SVG rendering, the chart uses React hooks (useState, useEffect) to manage state and load data via d3.csv, with interactive axes formatted using d3.format.
