This interactive scatter plot compares sepal dimensions across three iris species using D3.js. The visualization displays sepal length against sepal width, with color-coded points representing each species and a legend supporting hover interactions that highlight matching data points. Data loads from a CSV file using d3.csv, while d3.scaleLinear, d3.scaleOrdinal, and d3.axisBottom/axisLeft handle scaling and axes. The code includes a resize observer for responsive dimensions and BBC-inspired color styling.
