This interactive scatter plot visualizes the relationship between two selected numeric attributes of a dataset, allowing users to switch both the x- and y-axes via dropdown menus. The visualization uses D3 v5’s `select`, `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` APIs to render axes and circles, with a `transition().delay()` animation moving points to new positions. The data comes from a CSV file of weight and height records, loaded with `csv()`.
