This scatter plot visualizes the Iris dataset, comparing sepal length and sepal width across three iris species. The visualization uses a D3.js SVG rendering approach, with points colored by species using a BBC-inspired color palette. The chart includes interactive features such as a hoverable legend that dims non-matching points, and the code demonstrates the use of `d3.csv` for data loading, `d3.scaleLinear` and `d3.scaleOrdinal` for scaling, and `d3.axisBottom` and `d3.axisLeft` for axes. Data is sourced from Fisher's Iris dataset.
