This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across three flower species. The chart uses D3’s `scaleLinear` and `scaleOrdinal` for axes and color encoding, with species mapped to a categorical palette. Built with React, the visualization renders marks as SVG circles, with dropdown menus dynamically updating the X and Y axes. Tooltips display formatted values, while D3’s `csv` loads the data asynchronously. The visible grid lines and axis labels enhance readability, making it easy to compare species clusters.
