This interactive D3.js scatter plot visualizes the classic Iris dataset, showing measurements of sepal and petal dimensions for three species. Users can change the X and Y axes using dropdown menus, instantly re-projecting the data. The visualization uses `d3.scaleLinear` for axis scaling and `d3.axisBottom` and `d3.axisLeft` for tick marks and grid lines. Points animate from the plot’s center using D3’s `.transition().duration(1500).delay((d, i) => i * 10)` and are colored by species via the `.style('fill', (d) => color(d.class))` mapping, creating a dynamic, reconfigurable view of multidimensional plant data.
