This interactive scatter plot explores the Iris dataset, showing the relationships between four numerical flower attributes across three species. Users switch the X and Y axes via dropdown menus, and an animated transition moves the colored circles to their new positions. The visualization uses D3.js v5 with a modular structure, leveraging `scaleLinear` for axes, `scaleOrdinal` for species colors, and `axisBottom`/`axisLeft` for grid lines. Data loads from an external CSV file, with circles rendered as SVG elements and a legend identifying each species.
