This scatter plot visualizes the classic Iris dataset, displaying sepal length against sepal width for three species of iris flowers. Each point represents a sample, color-coded by species (setosa, versicolor, virginica) using blue, green, and orange, and includes interactive tooltips that reveal exact measurements on hover. The visualization is built with D3.js v7, using `d3.csv` to load the local CSV data, `d3.scaleOrdinal` for color mapping, and `d3.scaleLinear` to map data to pixel coordinates. The SVG rendering includes labeled axes, a legend, and smooth tooltip transitions for enhanced readability.
