This animated scatterplot visualizes measurements of gladiolus flower species, comparing petal dimensions across four feature pairs. The visualization cycles through different x-axis variables—corolla width, calyx width, corolla length, and calyx length—while keeping y-axis fixed to calyx length. Data points are colored by species, with red, blue, and yellow marking three distinct gladiolus varieties. Built with D3 v6, the example uses `d3.scaleLinear`, `d3.axisLeft`, and `d3.axisBottom` for axes, `setInterval` for animation, and SVG circles with custom `rx` and `ry` attributes to render elliptical markers. The code appears to fork an existing D3 scatterplot example, adapting it to flower morphology data from a CSV source.
