This interactive scatter plot lets users explore correlations among heart disease patients by selecting any two metrics from dropdown menus, which map to the x- and y-axes. Each point represents a patient, colored by heart disease status, from a CSV dataset. Built with D3 v7, it uses scaleLinear, axisBottom, axisLeft, and transition().delay().duration() for animated point placement. The chart renders in SVG with adjustable margins and axis labels.
