This interactive scatter plot explores relationships between variables like GDP, CPI, and birth rate across countries, with each point representing a country and colored by continent. Users can switch the x- and y-axis variables via dropdown menus and click legend entries to highlight specific continents. Built with D3 v7, it uses `scaleLinear`, `scaleOrdinal`, `schemeCategory10`, and the `axes` helper from `@curran/responsive-axes`, with hover tooltips showing country names. Data comes from the World Data 2023 CSV, and the visualization updates dynamically through D3's data joins and transition methods.
