This interactive scatter plot cycles through three blood-related measurements from a medical dataset, displaying a different x-axis variable every two seconds. The visualization uses D3 v6 with a reusable chart module that maps data points to circles, scaling positions with linear axes. It animates by calling a custom `scatterPlot` function with different accessor functions, updating the chart in place. The plot reads CSV data from a remote gist, and the axes are rendered with `axisLeft` and `axisBottom`. The circular markers transition smoothly between states, demonstrating a flexible, data-driven approach to multi-variable exploration.
