This interactive scatter plot compares two variables, with dropdown menus above the chart allowing the user to switch which data columns are plotted on the x- and y-axes. The visualization is built with React and renders as an SVG using D3.js v5, leveraging D3’s selection and axis-generation methods to draw the points and tick marks. The source data is loaded from a local `v3` dataset, and the menus are populated dynamically from its column names.
