This interactive scatter plot visualizes the Fisher Iris dataset, comparing sepal length against sepal width across three species. The chart uses custom D3.js code with `scaleLinear` for axes, `scaleOrdinal` for species colors, and `axisBottom` with `axisLeft` for ticks. The legend enables hover interactions that highlight one species while fading others. Data loads asynchronously from a CSV URL, with the visualization adapting to container resizing via `ResizeObserver`.
